The Unlimited car Insurance is a ****

I have a warranty polity with The Unlimited Car Insurance. I 1st ask them to tow my car, i was promised that a representative will call me and that never happened. Later on i claimed for the mechanical experience they never came through. Each day i make an enquire i am told that the claim is still under investigation or they will call me. This has been happening for more than 6 months now. They always have excuses. I had a mechanical problem last year they came with different excuses. Same this year but they always take the premiums
