I bought a pre-owned supposed unlocked Iphone 6 Plus recently from GameStop in a trip in USA, but when I arrived in Brazil and tried to work with a Brazilian carrier SIM I discovered that it was actually a locked phone. Then I called Apple to make sure it was locked and they confirmed it. Apple support told me to get in touch with you guys from Verizon who were the original carrier for this phone to ask to unlock. Please need your help, as I don't have a valid USA phone number I'm trying this communication channel, if you could give me an e-mail or the steps I need to follow so I can get in touch with you and solve this, I would be glad. I expect hearing from you. Thanks.
