Last week I found out by chance that with two weeks remaining from the policy expiry date it had been canceled. This was after I noticed the full refund in my account.After a weeks investigation and based on a call recording from last year it has now been voided. Have asked for a copy of the recording but they have yet to respond. The reason was wrong address on their system even though they had a copy of my no claims discount for the previous year and 27 years lived at the correct address. The obvious conclusion is that I have tried to have lower premiums based on a more favorable address, but I could have given them my relatives address in Northern Ireland. Instead they have a random address in Cornwall, a place I've never been to. Want to know where I go from here? If it stays voided then I will be paying much higher premiums for the foreseeable future. I have to balance this against my low mileage 4500pa and facing the upcoming expanded Emission Zone thing to the North Circular Road.
