excessive yearly increase

I have been a loyal client for over 20 years, only to be recently disappointed, more than a year ago i had a claim which was paid out but only finalised during the last year (due to Covid), when it came for my review of my policy i was surprised to see that they increased my policy by around 20 percent and they automatically upped the excess by 100 precent on my one car. i phoned to complain and was assisted by a gentlemen appeared to be so happy even when i explained that i found the increase excessive, he then did a recalculation and halved the increase however it is still as far as i am concerned excessively high and i now have to pay double the excess. the best part in trying to bring down my policy amount he ask me how much i would drive a year but that i was not allowed include the current milleage usage due to covid. which i find odd because my risk should be based on what i am doing now not what i will do in a years time. he did not seem to care that when i explained that increasing the amount of the policy was not financially viable to me as i like most of the country are experiencing financial difficulties due to Covid only being on a 4 day week etc... I find that Outsurance do not appear to care for their long standing clients, nor do they actually care that their client base may actually be experiencing financial difficulties. i found the gentlemen obnoxious and insincere. You know some of us actually buy insurance for the insurance and not the OUT BONUS I would like some of a senior position to contact me and re-evaluate my policy otherwise I will be forced to go to another provider
