Had my motor done on their last year also. They never got in but trashed the lock and bent my door trying. Cost - £85 for a new lock which then wouldn't fit because the door was bent, so had to pay to get that done too. There was clearly nothing inside to pilfer either which was the annoying bit.
Was told it was the first time anything had happened like that there for a long time, but after further enquiries found a number of others who had also had problems. Haven't bothered going back since as I don't like being lied to.
