Delay in my refund.

Last week Thursday I deposited money using Absa Atm in Braamfontein. The Atm took my money and said my transaction is unsuccessful. I went to the bank to lodge a complaint they told me I will get my money the next day. However I didn't get the money even today. I went to the bank twice this week and I am getting different stories from the customer care consultants. One of the consulates says after 5 days the other said it's not the bank's fault so I have to wait
