Hi Jon,
Thanks for the message and sorry to learn of the issues you have been facing after cancelling your policy. Could you please message me your full name / postcode and I can have a member of our customer service team look into.
Hazarding a guess I'd say having cancelled the policy whilst still 'live' you may still have had monies outstanding with the Finance provider and hence these issues have arisen. I'm hopeful we can sort though.
Thanks,
Dan
