Fuel Pump charging incorrectly

To Whom it may concern<br> <br> During this recession we experiencing not everyone has money to just throw away, in the past while filling up at a Fuel station i asked for R100 and yet the fuel pump puts in R100.05C, now because of the 5C the balance was declined while swiping for the amount and my bank charges me a penalty for being short of 5C, but after the banks penalty i do not have the full R100 any more to pay the Fuel station, When confronted with the question as to why the fuel pump does this, the answer is that the pumps are faulty, Yet this morning while trying to get to work i stopped at the Engine fuel station on Camaro street and asked for R100 petrol, R100.03 was put into my Vehicle, i then told the attendant that i will not pay for a faulty machines mistake, i was asked to please go pay inside where i was made to look like a fool by a person named Zahida, who said if i dont want to pay the 3 cents then she will pay it for me......********ly not knowing what iv been through, Yet i am a paying customer, How dare this person speak to me like this, If something isn't done about it, i will go out of my way to make sure people are aware of this service stations terrible service
