Enterprise Car Sharing

I had an awful experience with this service.
The last time I rented a car I picked it up in a garage further away due to limited availability in my area. The car was parked inside of indoor garage which was lit poorly. The car was dark grey color. I looked around the vehicle, everything looked fine, and I took off. I rented a car for a full day, and as soon as I got on the interstate and picked up the speed I noticed a very loud noise. When I reached my destination in suburbs I got out of the car and noticed that the rubber outside of a window on driver’s door was shaved off significantly, hence the noise. The color of the rubber was matching the color of the car, which made it pretty hard to see without direct light. On my way back to the city when I got back in the car I remembered the issue, and emailed the support team informing them of this. Two days later I got a voicemail from a rude lady telling me that I reported it during my rent period, which means I will be charged for this, and if I had questions to call back. OK. I called back, but the office was closed, I had to wait until Monday. I knew this was noted in the agreement, however I wanted to speak with someone regarding this as I believe it wasn’t fair — this damage even though significant, is not visible. In a few days I went to book another car and discovered that my account was locked. When I called customer service they couldn’t tell me why, and suggested to call on Monday. Well, I assumed it was due to the damage, however, wouldn’t it be fair if I was informed that my account will be locked? I counted on having a car that day, and I was out of luck. Thus far, my experience had been disappointing, not very customer oriented, yet, it gets worse! I tried reaching customer service office in Chicago a number of times, but could never get through. Left messages, nothing. One day I finally got through and a gentlemen who picked up was plain rude. HIs answer to all my questions & concerns regarding the issue described above was: you did this, you signed the agreement, you are wrong. As you can see, not friendly and not even understanding. When I asked for his supervisor he said that he is the manager of the branch and there is no one about him, and that there is nothing he can do for me: I will have to pay the $ 500 fee. He was rude, he interrupted me, and he hung up twice during our conversation. I was shocked. I was researching corporate address of the Enterprise when I got a call back from him, apologizing, and accepting my concerns. It was as if someone watching him talking with me, and made him call back and apologize. He took everything off my account & closed it. However, after the nasty experience with him, AND poor experience with the service, I stopped using enterprise at all. I used to be a pretty local customer, renting cars during my travel in the US & in Europe. Not anymore. There are plenty of car services, and this one might have a big name, but really awful service.
