Maybe your request looked illegitimate for some reason, and the request was silently discarded. The Faucet pretends to pay when it sees abuse.
The Faucet never sent the coins, so it's not a problem with Bitcoin.
Ya! Maybe... It can be anything. But i don't know.

The quintessential after this failture is, i don't try to integrate bitcoin-payment in our webshop, because the bitcoin-system doesn't seems to be trustworthy for me. A real pity.
