I sent from my adress to dispenser adress 0.0015 and 0.0004 to get a key but i can't buy the key because the transactions even if are confirmed didn't seemed to work, i don't have enough even if i send enough to buy a key, i even paid to a guy 1 tour of duty ticket to get 0.0015 especially to buy a tf2 key and didn't work..

Finally it worked after 1 hour, it can be closed!
