Pathetic service

From March I have been tying to put my account on hold. After numerous phone calls, emails, visit to the branch I have had no luck. My credit that was a large amount is now starting to run out and still no luck. I went to Vanderbijlpark branch again on Tuesday to now close my account, but still nothing. I am fed up with the pathetic service and I want my credit back. I am not going to pay anything further I want my account close and my money back......
