My car's bumper was hit and damaged before Christmas. I was stationary and the other driver hit the rear of my car whilst he was making a turn. Thankfully there was a witness and he admitted responsibility. I called my insurance afterwards but the other driver texted me to try and get me to sort it out ourselves, but his offer wouldn't go anywhere towards the repair bill. My insurance are due to pick up my car soon for the repair but a couple of days ago I got a call supposedly from his insurance company. They only asked for me by my first name, didn't mention where the accident happened or anything, just said that he admitted responsibility to them and asked if I would consider claiming through them instead of my own insurance company. They said that way I wouldn't pay and excess or affect my NCB. My insurance company have already told me in writing that won't happen as he has admitted responsibility. They then offered me £500 to stop my claim and get the car repaired through them. I declined their offer but I thought it really weird. I've had a few bumps during over 30 years of driving, and I've never had that happen before. Has anyone else had this happen? It just felt off.
