Poor service

In October 2016, my pension payment was delayed. When I enquired, I was told my initials on my ID document and banking acoount were different. I requested standard bank to rectify the error. It was done apparently for that particular reason. On the 23rd November 2021, Old Mutual requested me to provide a bank statement, to my surprise my second initial was still missing. I'm disgusted by standard bank. They don't respect their client, they mess up clients ' information. Why? I'm still to understand. I'm sick and tired of addressing one issue forever and ever.
