Blue label connect not complying with legislation!!!

Blue Label Connect has been phoning me non stop. 7 calls in less than a week each time from a different number so no more use in blocking their number. Initially I tried to explain why I'm not interested in another cellphone contract. Call after call, the call centre agents just drop the call. I phoned on Friday 22 October 2021 reporting a formal complaint. After receiving a second call on Saturday am (the 5th one in a few days) the call centre agent advised I can register on DMASA - opting OUT for all direct marketing which I did ... Just to receive yet another call! THIS COMPANY IS NOT COMPLYING WITH THE POPI ACT - I've confirmed MORE THAN ONCE that they need to remove my contact details. Where do I further report this useless company ? They clearly have no idea what is going on around them ????
