Ruining my car so I can come back

Took my car in for the radio to be checked only for my car to come out with two burnt light bulbs. I leave home when it's dark so I see the reflection on the garage and when I get home my light bulbs are dead ???? One main light bulb on the right and the gig light on the left???? I really love the service but if they going to do me like this then I'm afraid I'll take my car elsewhere ????????????????????????????????????????????????????????????????????????????????????????????????
