Paint damage from the workshop

Hi together, got my car out of the workshop and the next morning at the driver’s door found the attached paint damage (above the door handle). Of course I called right away and they said that the “master has to look at it” …. Sure, they want to talk out, so I want to be prepared so that they don’t feed me any false statements. Please for assessment, the bigger one is about 3mm. And what is best to do. It’s a 3 month old. I see the new car and the place every time when I get in. Thank you, Markus
