I had the same problem with the useless t***s at the dvla back in Dec. when I got mine. The dealer kept going in at their appointed slot to collect the docs. but each time it wasn't ready. The day they promised delivery I took a day off to collect the car & go for a spin etc & at 9.30 the dealer rang & told me that the dvla had let them down.
I ripped into the c**t cos they new on the Friday that the tax wasn't sorted but didn't let me know until so I wasted a days holiday :mad:
I made the f*****s deliver the car to me a couple of days later on a trailer & collect my part ex at the same time. Strictly speaking it wasn't the dealers fault but I was mightily p****d off with him cos he could have let me know earlier.
No consolation I know but at least you know you're not the only one who has had problems with the dvla
