I had an automatic renewal on my policy from last year. I thought I would warn everyone thinking of using RAC that my policy went up over £500 with no claims (!) and they took it out 5 days before the renewal was due, leaving me with no way to organise another policy as I had no funds left in that account. To get myself out of this and get a refund I've had to pay £35 cancellation fee and £35 admin fee for their mistake in taking in early (apparently the computer did it automatically on the 12th despite the renewal date not being until 17th!). I'm happy to suck it up to get the larger chunk of money back, but I didn't want anyone else to fall into the same trap.
