Pet insurance ****mers

i have had health insurance for my 2 pets with Dotsure for a few years. up until one of my furbabies got ill in the last 6 months or so- she had to undergo lotsa medical treatments. at the time of signing up with Dotsure a certain amount was allocated to each of the pets as benefits-at no stage --- and to date ..was the limits ever exceeded or exhausted but this week i get a letter from Dotsure confirming cancellation of my policy with them claiming ratio of claims. nowhere in the contract is the NUMBER of claims specified suffice that if the limits are exhausted then there will be no cover. my repeated communications to them has gone unanswered- they also cannot explain why both pets are now without insurance as i hardly claimed for the 2nd pet- as individuals we take medical insurance for the very reason ....MEDICAL.... but now that i have claimed WITHIN the allowed benefits i am told the claim ratio is an issue- no substantiation- no calls returned...no mails responded to...basically and literally giving the client their middle finger...not even discussion of increasing the premiums in order to facilitate the claims- even though we did not exceed the annual limits- to all the *****s of Furbabies- Dotsure literallly wants policies which has little or no claim so they can run their "profitable" business- and literally throw our sick furbabies under the bus
