Processing according to Parkrempler regarding the purchase of spare parts

hello professionals, sometimes a short description of the situation in advance. my car stood today on our side to park and my neighbor drove backwards into the side. exactly at soner stupid place, that kotflügel and bumper have to new plus paint. and while the just new due to styling was now my question. since I did not want to cause her any further expense, I inquired where the bumper is cheap again. in berlin was more expensive than at ebay. s he meant we do the private or over insurance. so I ordered immediately a new rod at ebay because I want to keep the cost stop in the frame. earlier she came over and meant the insurance would settle this and I would have to call Monday to tell through her name and license plate. then n comes to write and I can probably have it repaired. i.e. se innherlab a half year later can still make cost assumption and is not upgraded. how isn date nu? wars e n mistake to order the rod already privately? because I would otherwise order the plate because I certainly get cheaper than the paintr makes me price for end-consumers. n bissel is afraid that the insurance only accepts the bill of the paintr and I will stay at the cost of the rod… what do you say? was it wrong to order immediately? or can I make the privately procured rod valid? I hope that will work.
