Call the number on the letter that was sent to me asking for DVLC check code. The number issued was the wrong number! After speaking with 4 separate people I was given a number to call and was told again that Icwas through to the wrong department! I final got through the 5th time. After giving my DVLC code I was told it would not work, and I was asked for my driving license number and that felled to work. We all entered my NI details on your site and that came back as invalid, I’ve never had a problem in 35 years! Your wed site would not allow us to put details in or except details. The issue I believe has been resolved by entering the details on the DVLC site.
