Standard bank, at it again

in the year 2011, my garage card was the last time I used it, I called and got a settlement amount, and paid the amount and assumed the account was closed, needless to say after viewing my credit report I noticed the card was listed, I called standard bank, and got the settlement amount, on the 29/05/2015 I went into a branch and paid the amount, when I called to close the account, I was told that I should ask for a refund, and a service request was generated ***. on the 03/06/2015 I was sent an email stating that the service request was completed and called again to find out the outcome, I was told the refund was approved and the lady took my bank account details and said I should call on Friday to confirm, when I called today I was sent to 3 different departments only to be told that the account is closed and I will not get a refund! does the different departments not liaise with each other regarding what information they disclose to the customers? I was told that the money will be in my account on Friday the 12/06/2015, today I was told no refund! please get your stories in order as I WANT MY REFUND,
