What's the best thing to do if someone has cloned your plates? I've just received a letter through the post for a £100 car park fine from a Blackpool Hotel which is over 4 hours from where i stay and have never been, as I was selling the car i listed it on gumtree which is where they got the reg i'm guessing

The photo's were taken at night and while it is my reg my plate is clearly different in design, border/badge etc

At 1st I thought it was a scam but they must have contacted the dvla to get my name and address
