Spoke to someone at DVLA a few weeks back and they said it is probably in their backlog - he could not confirm they had recieved it.
I have tried repeatedly to tax the bike on line, only to be told I cant because I am entering the incorrect details.
Getting really pi**ed off with this, and to be honest have been riding the bike as I have got to the point where I really cant be arsed any more.
I'll be ringing DVLA again on Monday, no doubt get the same story.
Looks like it's going to cost me £25 quid to get a new one, or whetever the fee is.
