Here's you first mistake
1.whether you are making a claim or not, you must always inform your insurance company in writing
This happened to my son, he didn't inform them, as the damage was minimal (reg plate damage )
, it was also Direct Line and months later the person who drove into him,
made a fraudulent claim stating that he had run into him,.which was all lies
This meant months or wrangling with my son's insurance company
and the other insurance company
thankfully in time, the other person's claim was seen as a fraudulent claim,
but sadly my son went through months of agony because of it
You now have to prove what really happened, by witness statements , photo evidence etc
There's no answer as to why he waited 7 months, He obviously thinks he can try and get
money out of it,
Sadly there are insurance scammers out there, but hopefully your insurance company will see straight through this, but be prepared for a few weeks of phone calls backwards and forwards
