Hi I have recently posted my paper licence and photocard licence back to the DVLA to be endorsed. This was done within the 28 days as stated on their letter. I then received a letter on Saturday morning to advise me that my liecnce has been revoked as they have not received my licence. I called the DVLA this morning to ask what was going on, only to be told by 2 different staff that because off a "back log" there is a 3 week delay. So therefore i possibly will not be able to drive now for approx 3 weeks. Please can some one advise me Thank you
