Managed to speak to someone who was actually helpful, really to long to explain here but safe to say it is all settled - well nearly.
I can provide evidence (current insurance policies) that they will accept as evidence of me having only 1 accident - agreed with them that they will NOT take anything from my account until I agree, did not want to go into whether what they were doing was legal or not.
I have also sent a letter to the CRU asking that tell me exactly what they have on record against me as there are 2 other accidents listed that I am totally un aware of so I want to know where this has come from so that I can persue it.
Took about 1/2 an hour on the phone.
To be continued...............
