Theft of items whilst servicing

[b2tf]

Was speaking to a friend of the family today who said he is pretty sure a Ford dealer who regularly services his car is actually taking things from the car and not replacing them, or even swapping them for substandard parts.
Apparently the latest thing to happen is that his MOMO shifter on his AUIII was taken off and replaced with one of a different colour with damage to it, when he questioned this he was told that it had always been like that. Obviously not true when the shifter is red and the Steering wheel is Blue. The Service Advisor was confronted about it and claimed that he did not look in the car at all while it was being worked on so he couldnt take the owner's word over that of his mechanics.

I know he's spoken to the DP about it and also informed the police of the situation, so hopefully that will be the end of it, but Im wondering if anybody has come across this sort of thing before? I know I am always VERY picky about who I let service or work on my car, I always reset the odo and note the fuel gauge position just in case they decide to hoon around on my fuel.

Btw, I should say the Dealer in question is NOT the one I used to work at - I dont want to give any decent dealer a bad name so I wont say who the dealer is.
