Shady Behaviour making ******* Sales Calls

These guys are so rude. First of all the new POPI act prevents any company from *******ly obtaining people's contact information and calling them to sell them stuff. When they call you, they expect you to take your time to talk to them and hear about their product, but refuse to tell you where they get your contact information from. The moment you ask them where they get your information from, their tone changes, they drop the phone on you, such rude behaviour. What they are doing is no longer permitted by law, the audacity of this company.
