MiWay harasses with unsolicited phone calls.

Miway harrases me with their unsolicited phone calls. I have requested on several occasions they remove me from their list by they still call me. How is this even possible with the new POPI act? I just got a call from them again...I have blocked all their numbers but they still get through...This time the Call Center agent was rude and put the phone down in my face. Stop calling me!!!
