Good garage recommendation

[wavechaser]

This is my first post so I'd like to say hello to everyone.
As in the title, I hope someone could recommend me a good,reliable bmw garage in Home Counties or not far from them. I have got couple issues with my F11 and I am fed up with my local BMW dealer garage. First problem is with the breaks,it looks like front's and back's are unbalanced or one of the caliper is sticky but they (BMW dealer) thinks there are fine -yeah,right .
Second issue is with steering,local dealer did tracking twice and car is still pulling to the left (nothing to do with the road camber) and steering wheel isn't set properly.
I would think that these sort of the issues are bread and butter for most of garages and fairly easy to diagnose and rectify.
If someone could recommend a good garage that is customer orientated, I would much appreciate.
I have seen this list of independent garages https://www.pistonheads.com/gassing/topic.asp?h=0&... but don't know or ever have been in any of them hence my request for advice.
Thanks
