<prompt> Human: Hi all, hoping you guys can help me out. I took a rental car out from Avis and there were no issues when I recieved the car. Unfortunately, I backed up into something low so I didnt see it at night and theres now a rather sizeable crack in the bumper.I declined all insurance except the additional liability and I paid for the rental using my chase sapphire following their terms under 30 days, declined insurance which has the benefit rental car insurance. I dont have personal auto insurance. What do I do when I return the car in a few days? Will there be a large repair fee? Does my credit card company cover the entire damage cost? Is this covered under collision insurance.Im rather new to renting cars so Im looking for any advice. Thanks!  <response>: First call Chase and find out what they recommend and if you are truly covered.. My Amex told me to return the car and give them Amex contact to submit the information.When you return the car all they are going to do is fill out a report, they have to get estimates of damage and then reach back out.
