You can give them a ring at Gatwick (number is on the CAA SRG web site) and they ought to be able to tell you where your application is. This time last year they were taking 12 working days. If you are really keen to get it and can get to Gatwick then as soon as they have done the paperwork you can go and collect it.
In the meantime you can fly but cannot take passengers. Good opportunity to consolidate and do a few solo trips to nearby aerodromes!
Happy flying!
