Sell-your-cell / iPhone Buyback
They quoted me for my phone and sent packaging to mail it to them, everything seemed legit as I have sold my old phones similarly with success from other companies in the past (like Gazelle which is legit).
After a few weeks I hadn't heard back so I have been trying to reach them. The website nolonger exists and no one answers their phones. There are a ton of other complaints similar to mine.
This is a scam and they are stealing phones and getting away with it.
