Activation Lock of Seller is set on my iPhone
Hello,
Unfortunately I did not know that 6 years ago the seller had been registered my iPhone 6 device (Serial Number: F1*******5MV) with their apple id.
After resetting my device to clear all my storage, in "Activation Lock" page the weird email f*****@yahoo.com is shown and I can not login with my Apple id and do not access to the seller.
This device is bound to my iCloud (email@gmail.com) and I have attached its package to this ticket.
I really do not know what I have to do :(
Please help me with this trouble.
Thank you in advance.
