made to pay extra R200 for fuel

Car was requested to be filed up. The attendant was seen starting the meter at an amount of R200 instead of starting at R0. Thus the total amount went up to R303.30. I was robed of R200 in all. When we arrived at the station our tank was at 3 quarters to full so there is no way we could spend R303 to fill up. The tank capacity of my car is about 46l so there is no way this is true. We had to wait for 45 minutes for the manger to arrive and report this. Also the manger was meant to arrive at 8am but she ended up arriving 15minutes later even after she was called and told that there was such a problem. The manager who name is Neo claimed that there was no where any mistake could have happend at such cases.Management did not attend to us accordingly thus we are not satisfied with their service and we feel and know that we were ****** of aboutuR200.
