Auto & General doesn't want to cancel insurance

I tried to cancel my vehicle insurance policy with Auto & General for 2 month now. When I phone in I have to hold on for who knows how long without speaking to anybody. If you use the app to ask them to contact you they just dont get back to you. I have recieved 1 phone call from them, but the consultant that was handling cancellations was not at the their desk and they would have phoned back. Its convenient to recieve payment from customers after they tried to cancel, one of those companies that makes it easy to sign up, but never lets you cancel. Totally pathetic. Now I have to pay insurance on a vehicle I dont own anymore...
