Kwik fit!!! Arrghhhh...they are useless....they refused to repair a puncture on my 19",s as they couldnt guarantee "not marking the wheel" FFS a tyre company as well!! You couldnt make it up!
Took it to the local indy on the industrial estate...no problems at all.
Good luck with the manager...i sense a rant coming later because i know what there response will be!!!!!
