Useless Private Banking Experience

I have been a Standard Bank Private Banking client for ~15 years. Due to a steady decline in their service over the last several years (and general incompetence) I requested my private banker to close my accounts on 27 February. Despite several follow up emails and escalation to the Private Banking Suite manager my account remains open as of 17 March. A formal complaint was also lodged on the 12th of March. As per the Standard Bank website, the complaint should have been acknowledged within 24 hours with a reference number being provided. I have not received anything! As a Standard Bank Private Banking client you are severely limiting your ability to bank, because everything needs to go through your private banker, and if he / she does not attend to your needs, you're stuffed.
