Simple profile update is impossible!

All channels at SARS are pathetic! I have started getting emails from SARS for another person's profile so it seems they had given my email address in error. I need to remove my email from that profile so that i stop getting these assessment and OTPs but the feedback I get after holding on for 2hrs to the call centre is that nothing can be done and I need to wait for the other person to action. Pathetic service.
