Money will be frozen via smart-contract. I guess that spoort will do all they can to solve problem and everybody will be satisfied. If customer lied, he won't get money back, if seller didn't send/sent bad quality goods — he won't get money!
Similar question was answered already, but here you have it again:
Deceptions are excluded technically. When you make an order, your amount for that purchase is holding until you confirm a delivery. If delivery wasn’t confirmed by you, the merchant will not receive this amount, and smart contract will send your funds back to your balance. Also if there are some other issues, you can complain, and our support team will review your case and make the decision.
