I think you should give the phone back to the owner and try getting your money back because this might be a permanent problem , and the phone might have been used by the owner and he might have made an account on the iPhone . If you want to save money by keeping the phone , you can set up a appointment with The Apple Store and they might be able to help you out ! I hope this helps you , good luck .
