Product: Credit card

Two companies are involved. I will start with Dollar Rent A Car and then describe how XXXX XXXX XXXXXXXX has handled this situation. 

I rented a car online to use from XXXX XXXX XXXX XXXX XXXX XXXX from Dollar. The location was the XXXX XXXX XXXX. My brother was with me when we picked up the car. Unbeknownst to us, we were given inaccurate paperwork at the checkout booth. It seems the worker put my name on paperwork for an XXXX car, when I rented a XXXX and was in the XXXX at her check out window. I have videos of the entire car inside and out and both include the license plate number from the check out day and from the return day. I also have a video that includes the steering wheel with the XXXXXXXX XXXX  and the mileage of the car. I took this video because the gas tank wasn't filled. I have the worker who made the error that caused this mess in the video, but neither Dollar or XXXX XXXX will provide a way for me to send these videos. My contract was for a 12 day rental and I was charged for 12 days. The problem is that whoever rented the XXXX ( unless the worker messed up paperwork for more than two customers ) this person rented it for 3 days ( from XXXX XXXX XXXX ) and it seems returned it damaged. I was charged {$600.00} on XX/XX/year> for that damage even though I didn't rent the car. Instead, I was driving the XXXX ( with XXXX License plate # XXXX ) until my contracted ended on XX/XX/XXXX. When you turn the car in at Dollar, no one goes over it with you. I was told to just leave my keys in the car. I learned about the extra charge when I was paying my monthly credit card bill. Immediately, I tried calling Dollar but found it impossible to speak to a person at Dollar. Instead, all calls are directed to email them through their website, which I have done, repeatedly. I've only gotten generic responses telling me I'm responsible for the charges. Not one of my questions was answered or even addressed. At least 3 times, my emails show that I asked Dollar to provide me with the contact information to reach someone at their corporate office, but these requests were ignored too. My screen shots of my rental car and its license place upon pickup and return were also ignored. 
Next, I disputed this charge on XX/XX/year> with my credit card company XXXX XXXX XXXX XXXX and provided them with all my evidence. I also spoke to many of their representatives on the phone. I was told it seemed like I had a clear cut case. Yesterday, however, I opened a letter dismissing the case. XXXXXXXX XXXX  said they could NOT help me and I would be recharged the {$600.00}. I immediately phoned XXXX XXXX and spoke with the woman in disputes ( XXXX XXXX who was assigned my case, I said, I assume you spoke to someone at Dollar before you dismissed my case. Who did you speak with and what did they say? XXXX said she didn't contact Dollar. The fact that I spent days to organize and send 14 pages of evidence to XXXX XXXX  and this woman didn't even contact Dollar and ask some of the obvious questions I suggested, such as : If you insist " so and so '' rented the XXXX, who do you show rented the XXXX with XXXX license plate XXXX? XXXX also insisted that the charge of {$600.00} paid on XX/XX/XXXX was paid in person with a card with a chip. She insists that is the only way this charge was processed. ( THIS IS THE SECOND HUGE ISSUE. ) My credit card was in my procession, and I was in XXXX and XXXX, Michigan on XX/XX/XXXX, and NOT at the XXXX XXXX. My credit card shows a charge at a XXXX store in XXXX, MI on the XXXX. I bought sour cream for my friends making us dinner that night. We stayed with them for several days and so did the white XXXX that I rented! I explained this to XXXX with XXXXXXXX XXXX, but she just repeated, " Believe what you want '' over and over. It was infuriating. I told XXXX I wouldn't deal with her anymore. I said, I want to talk to your supervisor. XXXX hung up on me, and five to ten minutes letter I get a call. I said hello several times, but there was no reply so I hung up. Someone from the same number called a minute or two later. I said hello, and a woman said, " You XXXX XXXXnd hung up. I immediately called XXXXXXXX XXXX  and reported this. I have never had a call like this in my entire life. There is no way this is a coincidence ; XXXX is absolutely behind this. My XXXX XXXX was and still is soaring, and I have had a XXXX since last evening. I'm in a situation where I have been trying to resolve this mess for almost 7 weeks, and it is affecting my health. I couldn't work today. I was in bed all day with a XXXX. I need help with this mess. XXXXollar can't be allowed to wrongfully charge me for a mistake Dollar made, and someone please deal with XXXX XXXX XXXX  incompetence. Dollar doesn't care if the right person is charged, they just want their money. XXXX XXXX  has hired an employee who is not only incompetent but who is vengeful. Now, to add to the wrongful charge issue, now I worry about vengeful, XXXX, having access to all my personal information, since she is now having someone harass me on my cell phone. The person who called me a XXXX yesterday, called twice, at XXXX EST from the ( XXXX ) XXXX. I think XXXX asked a friend or family member to make this call. I don't know what XXXX is capable of next. Your directions stated not to include my personal information, but people who harass people over the phone like this don't deserve protection. Their number should be published.
