Why are you refusing to pay out my money?

Standard Bank is refusing to give me the money left in my account after I paid everything that was owed to them. I have received no help even though I went to the Cresta branch twice (last two Saturdays - check your customer logs). The first time I was told I couldn't close my account because of one outstanding transaction for R20 (a purchase for airtime to call Standard Bank). I was also told I could not provide details for an FNB account where my remaining money could be sent, because a transfer to another bank apparently couldn't be tracked. The second time, I was told the printer failed to print my receipt for the tellers and to email my details. I did so, being told the money would be transferred on Tuesday. Today I checked my account online to see there has been no movement. Why is Standard Bank refusing to give me my money? I cannot even afford petrol to come in to the branch again. Your service is a joke, this is why you lost me as a client.
