Auto and General not cancelling insurances

I have been a customer with Auto and General for 4 years now and i have thus far benefited nothing of them expect a higher premium whenever i need to change something. I have no found another insurer offering me much more however Auto and General is not cancelling my policy for me. This is utter bull**** to have to call so many times just to waste my time. Whenever i say i want to cancel they say the lines are bad and make up stories.

Not on Auto and General. How do i cancel my insurance now or do you guys just make people stick with urll out of frustration?
