The rental car location at the Charlotte Douglas Airport is terrible. The worst customer service experience. I rented a vehicle on August 4, 2015 and returned it on August 9, 2015 between the hour of 1:00pm and 2:00pm Eastern Standard Time. I accidentally left my personal keys attached to the rental car keys. I know that was my mistake. Anyway, I called the next morning on August 10 and explained the situation. One of the employees acknowledged that they had a set of keys in the lost and found. He took a picture of the keys and sent them to me in a text message. I identified the keys as being mine. He said the keys were found in another vehicle. I said that didn't matter if I identified the keys and acknowledge they are mine. He said, let me do my due diligence. I will email and call the customer who rented the vehicle after you to see if there were keys attached to the rental keys. He also tells me that the best way to get into contact with him is by email. He said the car was due on August 14 and that he would get in contact with me. August 14th comes and there is no call or anything from the representative. I call all day on Friday the 14th and was not able to reach anyone. I finally talk to someone on Monday the 17th. They say there were no keys in the vehicle and the vehicle was rented again and is not due until the 20th. I said the reason why there are no keys in the vehicle is because, the keys are in the lost and found and a picture of them was sent to me. Essentially what they are saying is, we will not send you your keys and you are just out of luck. They played games with me the last two weeks, they have my keys there and I want my keys. The customer service is poor and unprofessional. If there is anyone at the company with any type of clout, you can contact me at firstname.lastname@example.org for a possible resolution to this debacle. Utterly ridiculous!
