Obnoxious Call Centre

I received yet another spam phone call from a guy stating he was calling from \MTN\". The first call, he kept asking if I could hear him. After about the 6th time, I ended the call. He then called back and instead of getting on with the call or listening to me when I told him that according to POPI (Protection Of Personal Information) Act, he had no right to keep my data, he kept asking why I ended the previous call.<br> 1. I never asked for a call from MTN. BTW - I have much better service with CellC.<br> 2. I never sent them my data, so where did they get my data? This is in contravention to the POPI act.<br> <br> After informing this call centre operative of this, or at least trying to while he was being rude and obnoxious on the other end, I ended the call. He tried phoning back again and I simply ignored the call. Next thing I get an sms thanking me for signing up to \"Yello Mobile\". Did I sign up? No. Did I ask them to store my details? No.<br> <br> Has anyone at Yello Mobile ever heard of the POPI act????? Nothing like breaking the law!"
