supersonic Reviews 

I'm only giving Supersonic 1 star to write this review. I do not recommend Supersonic to anyone! I've been waiting for more than 2 weeks for the installion of my internet. No one from Supersonic has called to update me, and this is after I've been calkjng daily!!! What passpoor service!!! I'm disgusted!!!

I have requested on the client zone portal to cancel my Supersonic subscription because of a relocation. I have requested cancellation since the end of July, I have logged multiple tickets on the client zone. there are dates on when
i logged the tickets and how long i am trying to cancel this service. I have followed steps for cancellation. I get a call more than. a month later telling me i need to give more notice until end of Oct.
I get billed for not using your services since Aug and now you forcing me to only cancel end of Oct while ignoring my previous tickets logged on request for cancellation. This is shocking .

You will stop billing me and taking money off my account.

1 star is also too good for Supersonic. They need like a minus number, because that's how bad their service is. I paid for LTE connection and so far I received nothing. I then canceled the order and it's months and I still have not received a refund. Calling them is the biggest waste of time, because a I have yet to meet a more incompetent useless bunch of people. They make government workers look like over achievers. Supersonic is the biggest scammers or 2025.

Stay away from this company, company sends faulty equipment

Takes money from clients and does not provide a service

When you cancel your service for their error they don't send communication and you will most likely not get a refund

Fr@ud alert
Sc@mmers

Probably the worst service I have ever received. They gave me an MTN Sim, a TP-Link MR600 router at R519/pm. Ever since I Bought this router I can’t work because there isn’t any internet connection, mind you I paid in full and they make sure that they demand you to pay upfront before they send you their router. It has been 30 days and still no internet connection Supersonic has send me a new invoice to pay again for nothing. This should be considered a crime because their agents called me they promised me to be connected to the internet but yet there isn’t any connection. Not even 1mbps at least!
Supersonic do not know what they’re doing and if you love your business and your money stay away from these people. They will not solve your problems but they will take your money! These technicians are always confused and not well skilled. They only provide generic answers. Please sort out this problem immediately or I am moving to Telkom!
This is horrible I am losing deals and businesses abroad!

Agreed to switch to them. Been over three weeks of broken promises to get WiFi connected. Still nothing. And I can't run my business. And they not sure if they help for at least another two weeks. What a third world company

They blame Openserve but custo.er service is abysmal. Honestly not worth the few Rand saving with them
One of my biggest regrets ever

How can I give a 0- rating. Absolutely useless. First month and I can not work remotely, can't even stream.
Support department is useless and shrug their shoulders at 2 and 12 up and downloads respectively. Refuse to come and fetch their rubbish equipment, so I am paying for no internet AND buying cell data to be able to work. WHAT A COMPLETE NIGHTMARE! Stay away!

Without warning Supersonic cancelled my account, everything was paid up to date. After they realised my husband had passed away. It is now 5days that I am waiting for the cancellation department to close down the old account and then only can I new account be opened . I am also still wanting for the refund on my old account. Not very impressed with them, but it’s sorry to say that unfortunately I can only make use of them.

This is a warning to all if you are considering getting fiber then do not I repeat do not go with supersonic. They are not helpful with anything and lie about there contracts it is a waste of time and money and if you threaten legal action for there breach of contract they nail you in every possible way they can

The worst company they laid to the people and to me they said for only R999 a month you get 150mb upload and 150mb download 2 days after activation I don't het 30mb download logged 4 tickets and phone 4 time hey send he speed is not garented so why the f I'm I pay R999 For this supersonic.co.za bull shit no one said or mentioned the 150mb is not garenteed I mean wtf

I signed up and received my order on the 28/05/2025. Two days later the service stopped working, I have been without internet ever since, what frustrates me most is the level of service. I ignore the online reviews thinking it might be different for me. I called and called all the agents kept telling me it has been escalated and mind you that I'm working from home, this is ridiculous. You guys are the most terrible service provider. I am glad I took a month to month service this gives me a chance to cancel but regret that I paid already for a service that worked for 2 days.

Very unprofessional..my banking details was used for another client and their amount of 3000 was debited off my account instead of 399..breech of popi act...and to date nothing has been done even though I emailed every email address that I have found... they say escalated to billing department but I even emailed the billing department..think twice before trusting MTN or supersonic.

The staff at supersonic are totally useless. We haven't had internet connection for going to 2 months now. We have tried everything they suggested. It has been established that there is a fault with the router and there isn't anything more we can do from our side. Yet they keep telling us for several weeks now that they will send technicians out.

We have spent so much money calling their helpline. At this stage we just want to cancel with supersonic but we can't even get that done. They keep
making us go through troubleshooting steps we have already gone through over and over again.

When you call them they will tell you they have escalated the matter and will call you back. You call them to follow up, and speak with a consultant about the problem all over again. Thereafter you'll be told to hold on, till the line disconnects. It has just been a vicious cycle.

I find it shocking that a company like Supersonic is still in operation. The staff are just liars. They'll lie to you all day, everyday.

Please people don't ever attempt to sign-up with this company called Supersonic for fibre . Worst company ever. No communication. Never answer calls. No response on issues. How did this company get a license to operate!! I made 12 calls in 3 days to ask for help! They don't answer!!!!How did MTN or Vumatel align themselves with this nightmare if a company!!!!

this is the worst internet provider and they don't pick up the phone you listen to music for 10 munites and I had to end the call

I have been a supersonic client for over 3 years. Have had issues in the past with connectivity on my line where I had to log an ICASA complaint before they actually did something to fix it. I had a year of no issues and decided to upgrade my line to a 200/40 line which took a week to do (this was upgraded on Tuesday) after the upgrade I have had connectivity and stability issues on the line. And unable to get speeds over 2mbps. I called this morning and spoke to a gentleman who opened a ticket said I would have feedback by 11:00. I work from home and require my wifi for that and have not been able to work because of this. I called back a few minutes ago to get feedback and NOTHING has been done as yet. SO I have now given the ultimatum that this be rectified by 15:00 or I will be logging a new ICASA complaint as I am not going to be given a run around again for service that I pay for.

deserves a ZERO rating! Had this wifi for less than a month and everyday at night it disconnects and i have to call them literally everyday of which i am first put on hold for 20minutes before anyone can answer! i cant do anything that i took the wifi for in the very first place. Who has money and time to call a service provider everyday because of the same issue ?? i am sick and tired of this pathetic service and yet i pay for it...i need this resolve as a matter of urgency else i am cancelling and telling people never to touch Supersonic ever again...too stressful as if i need more stress.... urgently fix or i walk with many with me!

These people will steal your money even after cancelling services. Do not trust them.

I was just debitted on the 1st of April for R1300 on my account after having no service since february 28th. I had requested on the 25th of February to have my line relocated to a new premesis. I had absolutely no response from Supersonic even after trying to call the call centre multiple times and logging tickets online.

I then recieve a call almost 3 weeks later after moving premises to assist me with relocating my line ( do people think we can wait around without internet for 3 weeks?)

I even advised the agent i had to get another deal because i had zero support from your company. And i advised him my location to collect the router from.

I then get debited R1378 this month because your company is incompetent to assist with migrating my line in time? This is the most daylight robbery i have ever witnessed. My packaged only costed R479pm and i have now had 3 months worth of payments taken from my account!

Sitting with fiber that dont work and no tec to come and fix there shit
