bad service at Williams hunt the glen

after a breakdown, my car was collected for repairs by this dealer on 16 MARCH 2020. it was kept at the dealer till I collected it on 30 June. within 48 of collecting the car it broke down again and had to be taken back to the dealer. the weird part is that they said they did work on the cylinder head, replaced thermostat and housing, plugs and oil since the car overheated. they also said they replaced the turbo but to my surprise that's the first thing that went after collection. I've been sent from post to pillar with this matter. from people dropping my calls when I wanted to find out the progress on the repairs. this is the second week since the car was collected and I'm still to hear from them as to what's happening with the car. what makes matters worse is that ive had to seek alternative transport for all the time the car was with them for four months! no courtesy car whatsoever. I need someone to call me and explain why did they lie on the repair report and why is this issue not taken seriously. ive had it with Williams hunt. the level and treatment of customers is despicable. I'm gonna be taking up this matter with the ombudsman. this is totally unacceptable
