jet garage in haddington total joke

I went to the jet garage in haddington and put £10 in my car and usually this give me from empty 46miles but this time I got nothing at all. After looking at my gauge then immediately returned into garage and asked if theres a problem with the pump? She said why I said because no fuel has gone into it ! She said I must have pour it on the floor because it says on her screen it went in!. Im sorry but despite what she thinks tech does break down . I said toher come look at my gauge come look at the floor its dry she just said there is nothing I can do as they have no one to answer too. I use this joke of a company everyday and thought as they seen me every day they would be helpful but instead was spoken to like I was lieing and stupid. Spread the word avoid these garages bunch of rip off criminals where is the trading standards when u need them. Since using this garage ive seen at least 10 other who say same thing. They can get the police involved if u dont pay but who do we call when we dont get the fuel we pay for hmmm???? If anyone knows how I can get this sorted please let me know thanks and hope no one else getsscrewed over but while they continue to trade its def gonna happen again .
