Door Problems - Who would you trust to fix (NW)?

[PersonaNonGrata]

Hi looking for some advice on garages that you would trust your pride and joy with.

We've had some problems with doors on our T5 Beach (sliding door catching and driver door hand pulls out too far then jams). We tried out a VW specialist company in Blackpool when the sliding door handle failed completely, and also asked them to mend the catching slide mechanism but their work was pretty poor imho, so I'm now looking elsewhere.

Any suggestions? We're in the Preston region.
