ITouchSA complaint

I went to the "HomeMakers' Fair in Midrand, beginning of March 2024. I purchased a "tens" machine from a great sales giuy - Tawana. My father suffers from peripheral neuropathy and I have seen various Facebook posts in the past, claiming that this type of machine can provide some relief for his pain. I was promised by Tawana, that there is a 60 day back guarantee. I asked for an email confirmation stating this, which I got from his boss Fabio (turns out after doing some research that he is in fact the owner. I then purchased the product for R3,5k (a lot of money for me) Anyways 30 days later, I have a serious conversation with Dad, asking if it works or not, and he said that he did not want to disappoint me, but no it has made no difference. Next day I sent a WhatsApp to Tawana asking how to get my money back and get the device collected. He responded that I need to reply to the original email from Fabio and he will sort it out. Email send. No reply. WhatsApps sent to Fabio{I could see that he was online) but never answered. I then told him that I will complain in forums like this if he does not respond! Then straight away he leaves a voice note, ensuring me that this is not a ****, and that he is very busy, but he will contact me first thing the next morning. Last time I have heard from him since then - 02 April It is now the 12th, let's hope he is not buying time and waiting for the 60 days to expire?
