fair enough, there a two sides to every story i suppose.. im sure they would have diagnosed it before removing it, but anyway they wont ever get the chance to as it seems. the problem with the automotive trade (im an auto sparky) is if you say a approximate price and its not what you think it is and it costs more your seen as the biggest ass. i know with every phone and counter enquiry that you have to allow a best and worst case senario. anyway, dont want to turn this into a bitch fight , im sorry your experiences havent been as postive as mine. best of luck with it all, there are many good mechanics that work on these things, i have also used chapman and chapman, and charlies motors and been happy with both.
