They auto-renew unless told otherwise. I phoned their customer services and was asked to hold the line while the request was actioned. I was then told I would be passed to someone else who started to waste my time by asking questions about my new insurer. She then proceeded to cancel the policy rather than the auto-renewal - deliberately misinterpreting my request. She was very rude and said I would not get a refund for the remaining days of the policy. She said I would have to go back to customer services to get the policy reinstated. So they were deliberately obstructive when I said I would not renew.
