Harassment and attitude by Wilma for somebody else's account

I have been harassed by Wilma from Newtons Attorneys today for an account that is not in my name. The extremely rude Wilma went as far as to give me attitude, demanding that I must have employed the person she referred to and that is why my number is on his account! The irony is I don't even own a business to employ somebody! I confronted her and advised her that I will be reporting their business to the POPI Act as I did not authorize them contacting me, at which point she threw down the phone in my ear. I tried being polite and explain why I am not the person she's looking for. I will not accept this abuse by a total stranger giving me attitude for somebody else's account and will report them to the Information Regulator if they contact me again illegally. Get your facts straight first before contacting me again for somebody else! What's worse, Hello Peter is FULL of reviews for this business and their cruel consultants throwing down the phone on clients and speaking to them like they are rubbish.
