Std bank lies

Today i find out that SARS out assessed and paid out, i wasnt able to update my details because i changed my cell number in June- I phone my old std bank to ask them to reverse it because it should just be hanging and told my account of over a year ago was never cancelled - so they have take my sars money and tell me i must go and close the account because there is a procedure, the same procedure that was not carried out by Standard bank Beacon bay East London a year ago! i want my money reversed and my account close! i am so cross about this now.
