BAD POPIA PRACTISE BY ABSA

I have been receiving numerous calls,messages and emails from ABSA regarding someone called MRS FA MTETWA, despite many emails and conversations with their staff asking them to remove my details on their system. They clearly do not understand the concept of POPIA, as they detail everything in these communications, including quite sensitive information. I have been blocking their number, and spamming their emails, but they always find a way around it. If you have any account with ABSA, best believe your sensitive information is not taken with the outmost respect and safety. I have this woman's' ID number, and all details to do something sinister,all provided by th every bank she trusts and expects to at the very least, not share any information with a third party, without any proper channels followed e.g Power of Attorney document.
