After 6 weeks, I made the mistake of phoning them from my mobile, 25 minutes on hold!
Anyway, I eventualy got through to someone, and I was probibly a bit Greensleved up by then and was maybe not super polite and subservient, the lady found my application, said there was nothing wrong with it and it should be out in the next day or so.
So there you go just ask and it will be delivered in a further 6 weeks time!
IMHO if you hassle them, you just go down to the bottom again!
