Absolutely dreadful experience with Myringo. I tried to make a simple payment over the phone but the system did not allow me to do so using my phone and instructed me to download their app, which I refused to do so. 

Ended up using my partner's phone and wasted a lot of time trying to make the payment over her phone. This is unacceptable, businesses should reconsider using Myringo as their payment processor, because its a huge inconvenience for customers. Pathetic service.
