Would there have been a message on the OBC that said something about lights being out? Not to displace blame or anything but wouldn't your mom have noticed it as soon as the vehicle was started? The tech should have noticed it too but I'm just asking...
Mistakes happen and I'm sure if you had given them a chance, they would have owned up to it. Now that their phone is gone, you've ranted on the internet about it, I'm not sure what the outcome will be.
