Horrible service

I’ve had a Telkom cellphone contract for years and I’ve been happy with their service and product offering until now. I was offered a free Prime video membership for 12 months, when the 12 months ended in May 2025 I was told I would be billed for the prime video subscription. I went to the Telkom store at Mall @ Carnival and was told tho cancel on the prime video website, I did try to do that but on the prime video website I couldn’t because they say my membership is with a third party and I’ll have to cancel with the third party which is Telkom in this case. I then went back to the same store and the consultant told me that can’t cancel it on their side I have to cancel with prime video. I contacted their call centre on the 18/09/2025 and the call centre agent told me that they will send me a link that would take me directly to the cancellation site, that link still took me to the prime video website that still shows me that my membership can only be cancelled via Telkom. I then called the contact centre again and the agent I got said I must dial a ussd code and he’ll send an sms with instructions for the ussd code. I tried doing what was on the sms multiple times and it still didn’t work.
