POPIA: Harassing Phone calls Multiple times a Day

POPIA

I have received EIGHT UNWANTED phone calls in the past 24 hours with 5 different numbers, that I have to block every time and then you use a new number to harass me on.

I DO NOT WANT YOUR SERVICES!!!!

I have attempted to have my number removed MULTIPLE TIMES, but your people HANG UP every time I request my number to be removed.

How is this professional? WHY would I every want to do business with a company that harasses people ALL DAY and ignores their right to have their own number removed?!?!?!!
