Closing Accounts

I'm a prestige account holder at Standard bank, but have had such bad experience with them. I've decided to move my account to another bank due to all the problems I have experienced in the past. I phoned on the 22nd of August to close my accounts, but was told that I had to go into a branch to do this. On Saturday the 26th of August I went into Sunward Park Lifestyle Centre branch to close my accounts. The lady that assisted me tried closing my account while I was sitting in front of her but her system kept blocking her with a technical error. I have been following up ever since on the status of my account but have had no feedback to say that my account was closed. Why does it take this long to close an account? This is the reason why I am moving my business away from Standard bank, the service and feedback provided to customers are shocking. I don't believe Standard bank helps you to move forward, they rather help you to move backwards!!!!
