Dstv internet

I received my DSTV intenet router on the 24/01/2024 and everything was well and it worked perfectly. On the 27/01/2024 I started getting countless texts from DSTV saying that my sim is locked because of usage at an unregistered address(I haven’t moved my router). I tried calling and was advised to reboot the router, all this was unfruitful. I even went as far as going to their Edenvale walk-in centre where I was assured that my sim is locked and I would be able to connect to the internet; I still couldn’t connect after that. I went as far as going to the Randburg centre where I was told that there’s a problem with their system and I cannot change usage address as that was apparently what was the cause of the problems I had with my router. I have since been getting texts that the sim is now locked for usage in an unrecognised device. It has now been 3weeks since I visited the Randburg centre but still haven’t been assisted. I called again this week and was promised by the agent that he would “escalate” the matter and that I would receive communication; another fruitless promise. I’m very frustrated because on the 27th of this month I will be debited for a service I’m not receiving.
