paypal closed my case in the sellers favour yet they scammed me on an item

[paul_1973]

the item was not as described or advertised in any way shape or form... it was supposed to be a proper rendition of the Mandolorien helmet made out of plastic as they had shown in the pics and video and not some cheap flimsy and broken rubber item... I have tried to resolve it with the seller but they are saying that i have to pay full postage back to them in china... which is going to cost me more...

i tried to sort it with the dispute centre with pics of the item they sent me.. i have also found out on trustpilot that other people have had the same problem... so any ideas on what i can do now?? 

thanks

You didn't say if paypal found in your favour but told you to return it, if so then.......

In the event of a dispute you need to bear in mind possible return trackable costs before you buy from that seller / item / country because....

Paypal state this >>
PayPal is not obliged to reimburse you for any costs that you incur to comply with any of PayPal’s requests for cooperation for the purpose of resolving the problem (including, without limitation, costs that you incur to return a SNAD item to the Payment Recipient or another party as PayPal requests), although sometimes it may reimburse these costs.

Although they will compensate you for some of the cost if you have activated this at some point before you made that transaction.

You also have the option to do a chargeback via your card issuer instead of a Paypal dispute if you funded your Paypal payment via a credit card.
