You need proof that the sale you're mentioning was this effect

I bought this for a clean Secret to Everybody Gonzila and 30 keys pure and added some random csgo junk that he wanted because i didnt use it

The keys probably aren't showing up because I bought them right before we sent the trade off of marketplace. The taunt was a gift from earlier and I bought the gourd grin myself.
