Damage to the vehicle during inspection?

Moin, I had my Mokka for inspection in May. Tomorrow at 8. At noon came a call that the inspection would be finished, but if I knew that I had a capital damage on the underbody. In the afternoon I went down with my friend and took the damage in sight. Slashed up long-carriers, ripped open underbody. Shocking, really. If that had happened to me, I would definitely have noticed it, that would have been right. There is a presumption that the damage must have happened in the workshop. It could have happened when driving up a lift. Why is one informed about such a thing only after the end of the inspection? Of course, the friendly one points out all the faults. I can only call guesses! Unfortunately, thanks to Corona, there was no acceptance of dialogue. The whole thing is already with the lawyer. But maybe someone like that has happened already. easy someone knows someone …. The car is 2 years old and if it runs bad a total damage. LG [edited by MT]
