Unreliable old damage becomes a problem with new damage

Hello all, 4 weeks ago someone drove in at a red traffic light on the rear right on the rims/wings. I then immediately had an expert report at the Dekra and handed over to my lawyer. Last week now the first answer of the insurance of the damage causer, with the hacking about an old damage from a 3/4 year ago. At that time I had a hail damage and the expert noted under “old damage”: – side wall back right finishing But I wouldn’t even know that there was something about this “envelopment” myself, nor did I bother at that time with this little note in the report. Now I hacked right after the reviewer, what he wanted to see then, or if he took photos of it. His answer: “Hello Mr xxx, unfortunately I only have overview photos here, because it is a hail damage. According to my records, these are smaller envelopments, but because of their This is not due to the hail damage. On the overview photo from the back right they are not even visible. With kind regards” Tsja ….. and now ??? There was 100% no pre-damage, which at least seemed to me, or my brothers would have fallen into the eye ! We bought the car 2 months before this hail damage, and there was no finishing on the back right side wall during the purchase / inspection. The following insurance also writes, the Si e there repair-proofs and invoices want to have …. What should I do now???? … if even the expert of that time can not explain to me what he wants to have seen…. …to the further inquiries, whether he does not want to issue me something oficial, what I could give to the against. Insurance, which this old damage-mark was not a tragic big one, he answers me no more…. …that is to vomit ….. The actual damage amounts to over 4000€, since also track/ Fall back to the right outside of all standards… the insurance company is going to “crack” that statement and cancel what’s going on, and I’m standing there like a moron.
