Scammed by a Gameflip Seller - Can't even leave a negative rating!!

I’ve just traded with g6669 for a dota2 item that was supposed to have 15 charges but it was already used to the extend it is not even enabled to be resold on steam market!
The Gameflip bot autocompleted the sale and I couldn’t even leave a negative rating since I was just scammed.

Which leads to this steam market item: https://imgur.com/a/7pu9NZ8

However the ALREADY USED ITEM I WAS SENT IS THIS ONE (NO LONGER ABLE TO SELL, SINCE IT WAS PREVIOUSLY USED EXTENSIVELY): https://imgur.com/a/0nMcl27

The listing of the item showed as if it was a perfectly 35 OFF and based the price on the full Artificer’s Hammer.

Here is a similar listing of the correct (and complete) item: https://gameflip.com/item/artificer-s-hammer/0d6595d4-6772-4499-97fa-c0221440a548

Two options to solve this kind of SCAM in the future:
1 - ban sellers that are selling already used items as if they were perfect items OR
2 - stop comparing those used items prices to the perfect items that are sold on the Steam Market and put the used items on a different selling cathegory!!!
Please cancel the order and implement on of those changes above. I will retrieve back the item when/how you want, since I have no use for it (I wanted to resell it on steam market, but I can’t since it was already used by the seller).

@DarkKnight Could you please take a look at it? The item sold was showed on gameflip comparing the price to the unused Dota 2 item, but I received an already used item. I created a ticket when I created this topic but received no response yet.
