Frustrated customer

I have had a problem with standard bank having uploaded another person onto my profile.This problem as been from 2010, been to standard bank numerous occasions and they promise me it's resolved every year since 2010. Clint Petersen from complains department gave me a apology letter stating standard bank resolved this issue in 2018, only to find out I have been handed over to Norton attorneys. I have tried getting hold of Clint telephonically and via emails since Friday with no reply.
