Not sure who they are, However I am getting two / three calls per day from that telephone number. I have also had a few calls asking about my accident? What accident. I then usually hang up
Definitely a scam, Asking about a car accident I'd had, When I said I must have amnesia the lady still persisted that I could get a big pay up. After eventually telling her I hadn't been in an accident I asked for my number to be taken off their system, For her to then put the down on me. 100% a SCAM.
