We bought a couple of new iPhones for christmas, so I cleaned the old ones up today and put them on Craigslist. Got an offer on the 6 immediately. It was well-cared for, no issues, had a new battery done by Apple a few months back, always in a case with a screen protector, just flawless really. No issues, other than my daughter REALLY wanted a new one, and we took advantage of a Black Friday offer. I meet the guy at Target about an hour ago, he checks it out, had a spare SIM card, put it in, set it up, touch ID, passcode, etc. All good. Checks youtube, makes a call, complains that he can't hear, but was holding the earpiece to his earlobe?? I should have seen it coming... He's satisfied, gives me the money, on my way. He texts me on the way home. "Did you set the passcode?" I replied " No, I saw you set it up when we were standing there." "Now the touch ID and passcode won't work." He texts me again "neither work now." I smell a rat... I sent back "I don't know what to tell you. I sold you a phone that was working 100% with no issues, and you tested it as we were standing there." I think he's trying to pull a switcheroo with a dead/locked phone. I'm not having that crap. He will not be getting a refund.
