Isn't our DVLA just wonderful? On 10th September I emailed (their website) to ask for forms D2/D4 to be sent to me, after three weeks (they state 7/10 days) nothing, I again emailed them, nothing, so being a Scot I invoked the Robert the Bruce spider theory (try again) and emailed again on the 29th October, on 5th November I received 3 letters all posted same day with 3 lots of forms, so the moral of the story is if at first or second time you do not succeed, then try again.
