They are a claims management company. It's a polite word for 'parasite'.

I suggest when they next call you, you inform them that you are recording the call (whether or not it is true) , you wish to be removed from their database, and any further contact from them will be treated as harrassment, for which you will obtain a restraining order.

They contact you again, a whistle blown down the phone is highly effective, in my experience.
