Calum it would be easy for me to delete this post, but I won't. You're entitled to your opinion, and your side of the story is just one side of the story.
Far from washing my hands of you, I tried very hard to offer you a resolution which included funding a solution to your egr problem out of my own pocket (despite me not having taken a penny from you or ever touched your car). I did this to preserve my own reputation which I've worked extremely hard to build and for you not to feel like you're being ignored in any way.
You're insisting on a full refund without giving my mechanic the opportunity to even check the car and rectify any work. So yes in the end I suggested you speak directly to my mechanic and cut me out of the loop if you wanted to maintain this position.
If the job wasn't right you shouldn't have paid the guy and taken the car. However you feel about us, the fact is there are countless examples of happy customers who are more than happy to travel much further distances than you have to avail our services.
You may be right, the manifold may still be leaking, but without letting the mechanic see it.. How can you expect him to solve it? Please don't tell me your time is more precious than someone else's. He worked the entire day on your car into the late hours wrestling with seized bolts and everything in between. His time is also worth something.
I will close this thread here. If you want to give him the opportunity to solve the issue, just call.
Thanks.
