How to contact the person you just bought from on Ebay?

I just bought a Iphone on ebay and it's locked.

You can contact the seller by clicking on his name, then contact

I would also give them a bad review if they didn't say that, if they said that then you should have read it more closely.

Log in to your ebay account, go under "my ebay" then go to "Purchase History" click on the item you ordered then scroll down to "Contact Seller" and click on it. Should take you to where you can message the seller.

You bought a stolen phone. Don't expect the seller to help you, he's probably the one whole stole it, or at least he knew it was stolen. You can try reporting it to eBay. In the meantime, your stolen phone is a paperweight without the password. There isn't any way to bypass activation lock.

Check their eBay posting.
