Look closely at the image below. Look at the email it was sent from @cuponeria.com.br. That isn’t the real address of a UK Government agency.
Now look at the notice. Apart from your name and email the sender doesn’t know where you were when you (allegedly) used the road in a chargeable area. Nor does the sender know anything about the vehicle you were (allegedly) driving.
Plus they claim the contact number they have given you is “temporarily unavailable”.
All this scammer wants you to do is click on “Click here to pay” and give them your card details.
If you have accidentally clicked and filled in your card details, contact your bank immediately. Otherwise, just ignore this scammer.
