Telemarketing

I'm truly surprised that a financial institute would become so desperate to use telemarketing and phone people who has NEVER been a customer of theirs over a weekend and have the audacity to tell me that according to the POPI Act they may phone me. No1. No, you may not phone me as I've never given you permission to phone me. 2. You may NEVER phone anybody for telemarketing outside normal week business hours. 3. Where did you buy this database from to start phoning people?
