Worst service ever

After filling a full tank at Sasol Zambesi I swiped to pay for the fuel and the transaction went through successfully on my side, the petrol attendent told me that on he's side it didn't go through, so I had to swipe again as he told me the 1st one would reverse, I did as he asked but nothing came back so we spoke to he's "manager" Coenie Groenweld on the phone to assist us with the matter, he told us that he would resolve the issue the following day. I told him I need my money to book a place to sleep, and he insisted that there is nothing he can do for me, so he ended up switching off he's phone.
