Activation lock issue
So guys, I have an original proof of purchase for the device (iPhone 6) which is activation locked. Furthermore, I have original box (with corresponding IMEI identical to the one on proof of purchase).
I am the second owner of the device and I bought it from a friend. I made a request to disable the activation lock and this morning I got a reply:
"Apple is unable to complete your request to disable Activation Lock.
We will not be able to review additional requests or documentation associated with this device."
Who can help me with this issue and what kind of answer is this?
