Double billed

On friday 15 april we put in a full tank of fuel and went on our merry little way. Come sunday my boyfriend receives an SMS of two payments having gone off of the same amount at the same time at the station involved..<br> Monday we phone Absa, no he has to go in to a branch for it to be reversed. He goes in to the bank, no they cant do anything we have to take it up with the station. Met with a ton more excuses by the manager Rentia, we were told that we need the slip in order for her to do anything. We had a bank statement but apparently that is not good enough and according to her the transaction must have been before shift change and other excuses followed.<br> <br> Now please tell me, why I have to sort out a double payment where neither party claims to be at fault and I still do not have my money. I would like this to be sorted out, I dont care how, but I want my money back.
