csgo keys trading bug?

I was sending an offer of 20 keys to my buyer but then the offer shows 'item not available for trade',but my inventory shows 176keys ( it was 182 keys b4 i sent the offer),so then i sent another offer of 14 keys to the buyer then my inventory shows 165 keys. What weird is my buyer's inventory shows 0 keys he received.I want to know whats wrong with this? where are my keys? Do i still need to deliver 3 more keys to him?and why his inventory dont show my keys? and whats wrong with my trade offer?

=| Anyone got same problem with me?need help.
I posted a ticket on steampowered,several days passed no one answering.

That is... Odd

I would contact Steam Support

 

Over the past few days CSGO inventory has been experiencing problems. Also we can't see the ticket.

There's been a few cases of missing keys. Try opening your CSGO client. It showed up for someone after the trade he did before he went to bed was taking forever. What happened was the trade didn't go through but he was missing a dozen keys. He opened CSGO and he got them back.

Or try getting a different account to send you an offer. Try accepting it, it can be junk or anything.

Edit: In the future once you send a trade and it happens again, just wait for a few hours and see if it fixes itself or goes through.

You can check this site for more info when things are going slow. CSGO Services is what you are looking at. The other day its status was in critical, a day before that it was on delay (which meant trades took longer to go through).

 

I would definitely contact steam support because that's odd and shouldn't happen under any circumstances.

 

Steam support dont answer at all. I dont get my cs:go gift into inventory, but it is showing that it should be there, i wrote to support - nothing
