I sold my old iPhone 6 Plus on eBay and it arrived to the buyer on May 2. Today, I received a message from them stating they could not activate the phone as it was activation locked and they needed my help. I was positive I removed the iPhone from my iCloud account prior to selling and even more sure that I typed my password in in order to turn Find my iPhone off when I was erasing all settings. Anyway, I do still have the IMEI number and it is indeed showing on Apple's website that it is activation locked. The website tells me how to remove the iPhone from my account, which I attempted to do, but it is not showing in my Find my iPhone account in iCloud.com. What's more at this point is that I asked the buyer what message they were receiving and they sent me the message, and the e-mail that the phone is activation locked to is not mine, and it's an e-mail handler I've never used (only use gmail and iCloud, not hotmail). I don't know what to do at this point? Any thoughts/opinions?
