I changed my debit card but my aviva car insurance comes off that rather than as a direct debit (not sure why). When we moved house I got new house insurance and assumed they had changed the address on both house and car but apparently not- so when the card didn't work they sent me a letter to say my car insurance would be stopped unless I have them an updated card- but I didn't get the letter and so the insurance cancelled. But I didn't know! So I have been driving round for six weeks with no insurance. I damaged someone's car in a carpark and left them my number. She wants to go through my insurance but I have contacted them only to discover I have none! Where do I stand legally?
