My son booked a MOT and Interim service online for the 11th September 2019 and payed in full £112 My son dropped of his car a Vauxhall Corsa S Eco flex Reg. SH63 PLJ @ 08:30 11TH September at the Coatbridge depot.. He was contacted at 10:05 by the depot supervisor/manager Craig and was told his car needed a coil spring and a spec switch to pass its MOT. My son gave the go-ahead for the repairs but told the car would not be ready until after 16:30. My son phoned me and asked if I could collect his car as he was backshift and started work at 14:00. I agreed. At 17:01 my son text me and said that he was contacted and that the car was ready. I got a taxi to the depot and waited until 17:55 and then was told the car was not MOT’d or had the service done yet and could I come back in the morning. I asked why and was told by Craig that it needed a coil spring and a spec switch fitted and he didn’t have the time to complete the job even though the car was there from 08:30? He asked me to pay the bill at this time. I asked if I had to pay for the MOT and service also as I did not know my son had already payed it. Craig said as a goodwill gesture he was going to give my son 2 years free wheel alignment because his car wasn’t ready. I payed £250 which I thought was for MOT, Service and the two repairs specified, it wasn’t till I got home I realized that he had charged me £139.95 for what he said was a good will gesture. My son took the car back the next day but Craig did not speak with him. I phone the depot also just to be hung up upon. The wheel alignment was not asked for and my son did not want it so I don’t understand why this guy charged me £139.95?
