Mobile in africa is a nightmare

I bought a TV Stick from them, I paid, their delivery was quite speedy, this was at the end of October 2020. I opened the package, followed the instructions and got a "oops something went wrong" message. I phoned their offices and was told to contact someone in their service department . . . . delightfully sarcastic chap spoke to me as if I was a imbecile and then put the phone down on me. I phoned them again and asked them about their return policy. I was emailed a form and many emails and phone calls later I was informed that they have a 7 day returns policy and because it took them 4 (four) months to collect their product from me there was nothing they could do for me and can they send me their product back because they couldn't find fault with it.
