Having never had a problem with car insurance we took a policy out with esure, i'd heard of them, they sounded reputable so was happy to go ahead.
Six days into our new policy, we received a cancellation notice, I called up and they said that we'd used multiple addresses at the time of getting quotes on a third party website. Complete rubbish.
So, I have 'mutually' cancelled my policy with them and will never use them again. Steer clear.
