How Can I Skip using Samsung Account & Directly Access to my Phone after an Hard Reset?

[AC Question]

My phone is Samsung Galaxy Note 4 of AT&T, and somebody who was bringing the phone to me had started to use it using his own Samsung Account & Phone Lock Pin before he give me. This person who were using the phone isn't available currently to tell me his Phone Lock Pin and/or his email & password of his Samsung Account. I already hard reset the phone but it asked me to sign in to that exiting Samsung Account. So, what shall I do?

It is a security feature... you're only real option here it to contact the person who set it up for you and get the right credentials to unlock the phone.
