OMGWTFBBQ, etc. I can't believe I missed all this....
I hate these stories. I have had my fair share of trauma over car work too. Even with the few things I do bother trying to outsource.

Others have mentioned it, and I will add my voice to theirs, The place is a clown factory mate. Don't even take it back there unless you need to. Its not too much to ask that a workshop get on with the work you paid them to do, without damaging things.... That pipe is rediculous, and the excuse is even more pathetic. The whole prospect of mystery panel damage is just scary.
All I can say is I so very badly regret giving the last place I trusted with my car "1 last chance" Cut your losses, it can get much worse.[:(!][:(!][:(!]
