what can i do now?

Are you sure you had not redeemed the game and forgot about it? I saw you have Poker Night 2 in your Steam game list.

I'm afraid that we cannot provide much further assistance for you on this matter. Technically Dispneser.tf bots work at the same status as a normal Steam user, they do not have any ability to check if the items deposited come from legit money source. Valve has the final decision on revoking any specific game gifts, the same situation can also occur if you trade with any other Steam user not through Dispenser.tf.

You may try to contact the seller with the information provided in the purchasing history of your account in Dispenser.tf. But in your case we don't think the seller tried to scam you in any way.
