There are only 2 ways to unlock an Xperia with MXTP, either you remember the email and password, if you don't then you will have to contact your Local support, in this case Sony USA BUT since you bought this from Amazon, then it might be imported, if it is then Sony USA won't be able to help you.

Got it, you will have to contact amazon and Sony USA, it doesn't hurt to contact your Local support maybe they can help you.

On chat they dont provide information how to restore or unlock the phone

Where i can get this info?

like I said, there's only 2 ways to unlock MXTP, since its locked at a bootloader level, either through the Gmail account or sending the deice to Sony, there are no other way to reset the phone.
