Impossible to cancel nor return!!! Do not buy from them

Emailed and sent message via website to cancel, no response. Then I received the order a week later. I have then been trying for the past week calling them to request return. Every time I wait for about 30 minutes to speak to someone. Then the agent always promised to send email confirmation of cancellation and said I will be contacted by courier - however this then never happens. I’m on the phone for the 4th time as I write this review, waiting for 20 minutes now. Clearly this is a scam and their trick to never let you return or cancel any order?
