Has anybody else using this service been having problems having your private key funded?

I've used it a few times and previously had a very good experience buying small quantities of bitcoin, but the last order I made almost two weeks ago still has not been funded.

In the meantime, they've run out of stock, re-stocked, and subsequently run out again. I feel like I'm being swindled, or my order was placed at very low priority because I happened to buy just before the recent price explosion.

I really truly hope that's not the case.
