Useless DS TV router

I bought a DS TV router and it was delivered to me on the 11th of January 2023 today it's the 17th of January oli have been trying to get it to connect since from then by constantly calling DS TV and couldn't get any help. Today in th3 morning I was sent to MTN store to RICA my sim card but when I get there I was told that my sim card is already RICAred. I then tried calling the useless DSTV call centre I therefore requested to speak to the Manager I was then sent to Unathi Mcikizana, who advised that she will escalate the matter and it will take 24 to 48 hours for an escalation. Then that means I am paying for something that I am not using at all. All I want is to cancel this thing and I want my money back that's all.
