I was told to go somewhere else

I went to the service station to fill mt petrol tank and asked the petrol attendant for R400 only and i was charged R400.10 and i complained as it was not the first time this was happening the petrol attendant went to the supervisor and he was given ten cents to give me and i wanted to speak to her as i was speaking she said shes calling the owner and the owner tried to give me the 10 cents while i paid with a debit card and i told him that its not the first time this is happening he said there is nuthing he can do I SHOULD GO SOME WHERE ELSE AND WALKED AWAY.
