Scammer!!! HELP GM! PLEASE!!

SO GUESS WHAT!? ANOTHER FRIGGIN SCAMMER!

so this guy Rylemasters was selling his ABG SWORD and i offered 40b!.. our method of buying/selling is by putting up a private shop and sell an item for 40b. so i bought the items for 40b but that wasnt the ABG Sword cuz thats not how it works, as u can see on the second image, it says on the right side "You spent 39,999,999,960" i spent my 40b. so right after when i did that.. he immediately moved >.> I DIDNT GET THE ABG SWORD!!!!!
he even whispered me as shown on the second image saying "thnx for teaching me how to scamm"
is this proof enough?
