To my understanding all these people have is the OP’s name and phone number. There’s no proof on their end the OP did anything.
What could come out of all this is… nothing. They claim to have already “fixed” it so there’s nothing to assess by the insurance company. Call me crazy but as far as I know insurance companies don’t just go paying claims willy nilly on someone’s say so. In my experience they want to inspect the damage themselves and in this case there isn’t damage anymore. The OP could block their number and that would pretty much be the end of it. That’s not what I’m suggesting the OP does, they have to make that decision themselves but at the end of the day all they really have nothing he said/she said.
