Raise rims scraping / denting after tires…

Hello together,in advance, of course, I know that you clean your rims in advance and I should have seen the problem earlier, but that doesn’t change the fact. So please stay with the topic, thank you. In mid-April 2016 I had new tyres with rim protection mounted on my original Audi rims. At the pick-up I saw that the rims are dirty (probably a grease oa.) from the. Only after about a month I then mounted the rims on my car and did not It was still the fat on the edges after several washings in the wash road, which didn’t bother me any further (because of the rim protection of the tires you couldn’t see that much anyway, only when you looked more closely you noticed that it didn’t belong to the tire/the rim). Now it is that under the fat apparently were hidden rickets and maces and these only now when the fat goes off so slowly to the appearance / are visible. Now w I should like to know if, after the long time (>4 months) of the company that pulled the tires on the rims, one can still account for it at all, or if that is already “priority” or so to speak?In addition, there is the question whether one can prove that somehow the mistake was made by the company (I can say 100% that it did not happen to me, say Randstein-Schramme oä., that is unfortunately no proof…)? But it can only come from there. Thanks already once.
