It would seem your biggest mistake was to settle for a partial refund through eBay. My suggestion would be to take it up with eBay again through their telephone support. Explain you mistakenly settled for a partial refund when realistically the phone is contracted to someone else & the company it's locked to have refused to unlock the phone.
Also HEK is right, don't pass this onto someone else. This could be solved through a long phone call to eBay.
Yeah, i ended my ebay listing for the phone, it is not on ebay now, I went with asking for a partial refund on the suggestion of a forum member here in mac rumors when i was asking about this phone being locked.
I dont know if i would get anywhere with ebay, they closed the case, do they open them again?
I also managed to get a hold of the seller, and i mentioned negative feedback for them since they have received 2 from buyers after me, and they got right back with me saying if i gave them back the money that was partially refunded to me, they would pay off the phone and get it unlocked, i replied back to them that if they did these things first and the phone is successfully unlocked, i would give them the partial refund back, because i how do i know they would get the phone unlocked for me once they got that refund back again? they might just take my money and run again.
