Ok heres the story. Went to the garage on Monday put petrol in my car and brought some other stuff. Paid for this but then upon going back there yesterday the person behind the counter told me they hadnt charged me for the petrol and I owe them money!? I was a bit shocked as I did at the time give her the petrol pump number and the value? Would you pay up and look big or would you dispute it as it was their error?
