Breach of POPI ACT

Clear breach of POPI ACT!!! These people call us claiming that they received our numbers from our colleagues. Even telling us what kinds of vehicles we are driving and our colleagues names. That information is very private and a clear breach of the POPI Act if they managed to source the information. I called the colleague in question and they stated that this company used my name and stated that I gave them their numbers as well. I'm really upset at the shenanigans these people are running!
