Hi, I'm hoping for some advice. I've received a debt collection notice for an unpaid parking fine. This was sent to my home address however I didn't receive the PCN as it was sent to a previous address. I updated my V5C in September after getting married with a new name and address. I am trying to get in touch with the DVLA about the exact date. I have copies now of the PCN, the first one was sent on the 12 Sept and the second on 11 Oct. By 11 Oct I am sure my v5c was changed. Can I challenge this on the basis that they should have used the new address then?
