Hi Flyboi. Welcome to the forum.
Sorry to hear your player is hacked. You can file a claim with eBay for the item not being as described.
But if you paid by credit card contact your credit card company. Tell them what happened and ask them if you can do a charge back. They may ask you to return the player. Tell them you contacted the seller and he wants you to pay for the return shipping even though you are the victim of the scam. Tell them about the hacked memory scam.
At this point they should start the charge back immediately without you having to return the player. Once a credit card company finds out your the victim of fraud they act very quickly on your behalf.
But if you didn't pay by credit card the only option you have is to file with eBay.
The selller on eBay offering you a partial refund, that is part of the scam.
There is a guide on eBay called The Hacked Memory Scam Guide. When I saw your message here I emailed the guy who wrote it, his name is Zeke, and I told him what happened to you and asked him if he would email you the guide for free to help you out. He said yes.
His email address is
hackedmemoryscam@gmail.com and tell him your Flyboi from mympxplayer.org. He needs your email address to get the guide to you. In the guide is info about what you can do if you have a hacked player.
Let us know how things go and don't hesitate to post here on the forum. We are all here to help. And email Zeke for sure and get that guide. It will help you a lot.
