Refusal to ensure me based on six and half year-old risk rating and failure to explain why the risk rating is not being reviewed.

I have been claim free for over 6 years now and consistently insured during this period. I was a previous client of OUTsurance and left prior to this claim free period.

In August 2019 when i requested a quote I informed them that my current insurer at the time cancelled my insurance due to excessive claims, this resulted in OUTsurance rating me as high and therefore not insurable. Six and half years later with uninterrupted insurance and being claim free for the same period OUTsurance still refuses to insure me and keeps on claiming that TC's apply.

How can I still have the same risk rating six and half years later with review of my risk rating. Regardless of the TC's this is pure ************** on the basis of exercise insurance claims cancelation by another insurer as if I'm not supposed to claim on my insurance, without a review of risk rating.
