Let the RAC know, then raise a claim
If you have not already, you need to tell the RAC that your car is not drivable, so they can send someone to help you.
You can report this online(opens in a new window). You’ll only need to enter a few details. You'll get a confirmation call and text, plus regular updates on your patrol's arrival.
Or you can call RAC Motability Assist on 0800 73 111 73. They'll try to get someone out to you within 45 minutes, but this can vary at busy times.
Once you've done that you'll need to raise an insurance claim with DLM.
