Invalid BOOM! HEADSHOT!

So I went to a trade server yesterday looking for a key, and some guy said his friend was selling them for 1.33 and I gave him the metal to get it. He then came back and said his friend changed him mind to 2 ref. And then the friend said he would give me 6 keys for my s sniper, and 10 ref for like 20 weps, so I gave it to him and he said he would pay me on Sunday because his keys were unusable until then. He unfriended me and blocked communication so he scammed me.
