Re the Spectator, on one occasion when I won a few years ago, I contacted the magazine after a lengthy period of time had elapsed to ask - since I'd never won it before - how long it was before prize-despatch usually occurred.
I don't know if it was just because I hadn't noticed earlier or because my query inspired it, but they then 'started' to print on the online crossword page that the delay would be six weeks.
Ten weeks certainly does seem excessive, so I should go on asking them about it and, yes, you DO deserve the prize!
