Seller not contacted me for a day since purchase

I bought a item for rocket league of someone for a dollar and he has not got back to me in a full 24 hrs since purchase

Is they anyway I can get my money back

Scenario A:
You buy the item -> Seller marks item as delivered but doesn’t deliver anything -> You open a dispute and wait until Gameflip resolves it. If you close the dispute then it will finalize the purchase and you will not get a refund.

Scenario B:
You buy the item -> Seller doesn’t do anything -> You wait until the “Seller sends in X days” is past and cancel the order.
