i feel sorry for you as you bought your Forester knowing that the clutch was replaced but then this...
cowboy garages are they but how trusted was the seller? was it the previous owner not wanting to spend too much £?
same goes for the so called FSH. it still to the owner what to do, i.e. no extra work only the bare minimum to get the stamp in the book etc
glad it's all fixed thou and you found a good garage, well done
good on you,
