Feeling harassed

This is the 4th time now I report this blue label connect I think i need to take further harsh steps now because I won’t be harassed like they do, I don’t even know where they got my number and been asking them to kindly remove my information from their data but I still get calls everyday from them, I really feel harassed the next step I am reporting, according the POPI act that is not allowed next I get a call I will deal with the accordingly.
