Engen Garage Beyers Naude next to Honeydew Police Station

I put in petrol this morning and paid with my cheque card. Their machine was faulty ; my account was debited but the guy claimed to not have received the funds. We tried again but unfortunately the 2nd time ; it declined because of insufficient funds as there was no money in my account anymore . I called the bank in front of the manager / owner and the bank confirmed the transaction was successful. I even showed him from my banking App that the account was debited . He did not want to listen and kept on saying I have not paid . I made a plan to pay from my other account ( different bank ) and the transaction went through . They now owe me the initial transaction cause I cannot reverse it from my bank . I do understand that sometimes glitches happen and there is a process so I can get my refund . The process is that they need to reverse the transaction on their side or call their bank to reverse it . Bit they were unwilling to do this . I need my refund and after going through what I went through ; I doubt if they will even listen to me again . Hence this write up here . This was at Engen Garage on Beyers Naude close to Honey Dew Police Station. Their service towards this transaction was very horrible . I was treated like a ***** who did not want to pay ; but the funds are sitting in the bank account .
