Activation lock

Hi Jossiel007,

Welcome to the Apple Support Community. Unfortunately this device can only be activated by the owner of the Apple ID which the device is locked too. This is done if the device was stolen and then erased or if someone forgot to turn off Find My. I do apologize for this and wish you the best getting your money back. I'll also include a link explaining Activation Lock for more information.

You need the Apple ID and password, or the original purchase receipt and matching ID and a discussion with Apple.

Activation Lock is a theft deterrent, and it wouldn’t be a deterrent if it were easy to bypass.

You probably got scammed, and if the seller is now unavailable, well, that’s fairly typical of these cases.

If there was a forum or other service used to connect with the seller, contact them.

If the local police are an option for you, you could report this to them.
