Is it possible to activate this disabled iPhone?

Ok so I brought this phone from eBay and it said used phone in good condition. I finally get it and when I turn it on it says iPhone disabled connect to iTunes. I tried it but it said I never had the phone trust my computer so it won't restore it or fix it. This is my first iPhone and I was trying to be cheap and avoid 2year contracts now I don't know what to do and I'm still waiting for a email from eBay about the return policy since it said no returns from seller but they lied/neglected to mention this issue any advice would help

You should not buy such expensive things without any warranty. However, I know a website which is genuine and can help you. UnlockmyPhoneHQ is the best site for official iPhone unlocking using iTunes. You can use it for any iPhone model and on all networks worldwide.
