Hertz rental car issue, am i ok guys?

It was your responsibility to check damage also you should have opted for insurance. You never know when you get in need of it so its always better to take precaution but all that's past now. The best thing you can do is call their customer care and explain them the whole situation. You can do anything now it depends upon them now whether they agree with you or not. Hertz is a good reputed car rental company hope they will agree to you.
