I'm a noob user who made my first trade yesterday. I sent BTC to my wallet and bought a few TF2 keys with it. Transaction ID 184944. The BTC was withdrawn from my credit but, as far as I can see, the keys weren't given to me anywhere. I have no items under my inventory, no key credit and I did not receive any trade offers directly on steam.

Am I missing something? Could someone explain how this works?

Many thanks.
