Cancelled without my concert

I am so mad with auto and general , the poor service , it took them two months to give me feedback about my car . I have two cars insured with them both involved in a car accident and they don’t want to pay for neither one of them yet I have been paying my insurance monthly and the last debit order was last week. I really need answers and call recordings I have been a loyal customers with 3 cars insured under them , I recently bought a new a car and this is service and thank you I am getting, I was informed today that they have cancelled my policy without my concert . I would really like them to give me proper feedback before I take this matter to my lawyers and social media because why pay for 2 years and when I experience a problem I’m told I won’t be assist ,rather they cancel my policy. If so I need my premiums back so I can fix both these cars cause now I will be paying for something I won’t be using
