Bait and Switch?
I received an on line estimate of $70 for my Iphone 8 Plus. I shipped it to Buy Back Boss. A couple of days later I received a message from them saying they would offer me $18 for the phone , indicating that the phone was cracked in the back. I asked for them to send a picture of said damage because I was not aware of any wear and tear on the phone. Particularly because the phone was always kept in a wallet/carrying case. The picture they sent me was not one of my phone. The phone pictured did indeed have damage like they said but it wasn't my phone. I didn't bother fighting it- they said they would offer me $30 for the trouble-a far cry from the $70 on-line amount I was initially quoted. My advice is if you use this service take pictures of your phone BEFORE sending it to any Buy Back phone service. At least you will have a record of what your phone actually looks like and can contest any estimate discrepancies.
