I've been scammed

I’ve been scammed by I love crates.Bought biomass for ten dollars and said he would deliver in one day. It has been three and nothing has happened and he ignores me and other people asking for items we bought on his page. I know that because he has posted more items for sale for example two hours ago. Gameflip has put purchase on hold but has done nothing!!! NOTHING!!! It’s pissing me off cause I don’t have much money what do I do?
