First day with new car, same as paint damage due to foreign debt 🙁

Hello together, I received my new car today a few hours ago, a 2 years old Clio III in mint condition and only 16.000 kilometers on the speedometer, with guarantee. Since I was still overcautious by the new car today I had been looking for an extra wide gap when shopping where actually nobody could get to my car. So after 15 minutes we come back and the rear bumper has the scratches that can be seen in the photos. I don’t know wi e blind someone can be that he is long cut, the Clio is also not particularly long and does not stand out of the parking space – or was it vllt. someone with bicycle pedals? From the height and shape that would be conceivable. I could almost howl, of course it is not a Ferrari or Mercedes and I have been driving regularly for 12 years, but before I had always used the cars of my parents or after that, which was here the first completely self-paid driving eug. If someone has a suggestion which would be the cheapest way to get rid of it with such scratches, there are in the space Berlin Spot/Smart-Repair Workshops that you can recommend to me, even the old Megane II station wagon I had before, had not such a scratch after 7 years and at least almost 180 000 km on the clock and with which here on the first day today 🙁
