Complete disregard when asked to remove me off of their database. Completely in violation of the POPI Act.

I have been cold called almost every single day from this call centre and I have asked them several times to please remove my number off of their database as I do not know where they obtained my contact details from and I have told them that I am not interested in what they are offering. I block their contact number and then they just call from another number again. It is incredibly frustrating to have this ongoing for months and then you are also dealing with their employees who are quite rude and pushy when you have nicely told them that you are not interested.
