POPIA breach

I have been receiving endless marketing communications from FNB within the past year, despite not being a customer of theirs for over 7 years and sending a formal request to have my personal details removed from their database they are continuing to contact me. This is a direct violation of POPIA. I am not a customer of yours or any affiliate, I don't want to be, I have requested you stop sending me communication and bothering me. But you just ignore it.
