I took my car in for MOT and miserably failed. They said "ooh, the engine doesn't look good at all you probably have serious problems with that car". I took into my normal garage and told them to have a look. They said that it was the catalytic converter so I let them do the work, then the garage called and said that it's not just one catalytic converter but two of them. So I shelled out just under £500 for labour and materials. They call to say that it's done so I pick it up and took it back for MOT. When I drove in with the car the MOT people said that they can tell by smell it's not fixed. But they put it under computer and of course it failed again. I took it back to the garage furious and left it there and told them to let me know what is the matter with the car. Now they have called me to say that car needs a lot of work and it would be much more than the car's worth.
I feel that I paid £500 needlessly if I wasn't going to have my car back to begin with. I feel as though they have taken advantage of me and did not check the car thoroughly and properly to begin with. I don't want to go in there like mad woman but want to go in and be reasonable. Basically I want my £500 back from them but maybe I'm bing unreasonable. Any advice would be appreciated.
