How can I bypass the FRP help!

So recently i bought i used phone off someone which had been factory reset. it was all good and all dandy till i got to the connect to Google account. So i dont have the owners contact at all since at the time of buying it everything was good, showed me it worked so there was no need to exchange contacts so we reset it. Now i cant get passed the FRP all i have is the IMEI and really nothing else. Would there be a way to bypass it or am i doomed.
