[Resolved]  Skoda — The cost of the repair

I bought the skoda fabia from a honda garage in barnsley it was a 53 plate tdi, after the six month waranty had expired thats when the problems started.
1) crankshaft sensor needs replacing
2) camshaft sensor needs replacing
3) base of engine needs replacing
this was due to someone putting the belt on incorrectly ive been in touch with both skoda and honda to help me pay for the work done on the car but both said they wouldnt pay anything the total so far £5,000 which is disgusting
