Cable drum left in the parking lot, brought in bmw.

Hey guys, I had a construction site last night where I had to get electricity from somewhere else and so also a cable drum had to come. When the construction site was cleared at the end, I left the cable drum in the parking lot and I went in to the house to get the cable out…. In the time someone was driving against the cable drum. However, the cable drum was standing at the head where you actually didn’t get it at all. it was not even his parking lot. Now there’s a fat bill of 2700 euros for two scratches that can’t even come from the plastic cable drum so from the height. The whole thing is still being checked anyway and everything would interest me, what is said?! MFG
