I booked my car in for a re-gas using a Scoupon Voucher. After the re-gas the front desk man said my ac valves both needed replacing ($25 each). My b/f asked to look at my car to see the leaks and we both walked into the workshop out the back of the store where my car was quickly driven off. In the confusion the attendant said the leaks must have already been fixed and we were not charged anything extra. We are happy with the re-gas.
