I insure her ladyship's car with L&V via the CSMA.
My car, being a lease agreement with Motability, is insured by them with someone or other ~ I care not.
When I had a claim on the motability car (some dozy bint backed into my stationary vehicle in a public car park) her insurers (Sheila's Wheels ~ wouldn't you have guessed it) tried this stunt, with increasing aggressiveness. Told them to p*ss orf several times, then they tried to weasel out of paying my excess of £75. I threatened to sue and they finally paid up and a week later they paid up again ~ (I kept quiet and banked the cheques)
