Weche Versicherung hesitates the most the damage regulation?

Hello together, what experiences did you have with the individual insurance companies during the damage regulation? I was hit by a road user on Fridays, the accident opponent immediately reported the incident to his insurance, when then ONE !!! week later my workshop asked for the damage regulation at the insurance company, they allegedly didn’t know about the accident yet. 20 years ago I also had a non-inflicted accident, dor t I got the money from the insurance only after I threatened with my lawyer. What experiences did you have in the damage control? Good ride Gerd
