Product: Credit card

On XX/XX/XXXX I rented a car for 4 days from XXXX. According to the contract, the invoice for 5 days was XXXX Euro. My credit card was charged XXXX Euro. A difference of XXXX Euros because I did n't return the car with a full tank. On XX/XX/XXXX and XX/XX/XXXX, I contacted XXXX regarding XXXX Euros and I explained that there is a mistake. On XX/XX/XXXX I filed a complaint regarding an unrecognized charge of XXXX Euro ( around XXXX dollars ) with Chase, the issuer of the XXXX credit card. On the same day, when I called Chase, the Chase Card Representative noticed and informed me that XXXX car rental company charged me {$440.00} again on XX/XX/XXXX for renting a car in XXXX. Because I did not rent a car from XXXX XXXX in XXXX XXXX or traveled out of the country, I filed the other complaint form regarding the {$440.00}. I called XXXX and the representative told me that " I rented the car in XXXX in XX/XX/XXXX '' I tried to explain that this is not true because I was at home in the US, but I was told they would not reverse the charge. 
Interestingly enough, on the XXXX Chase credit card statement, XXXX credited me, the XXXX Euros ( around {$85.00} ) the difference XXXX overcharged me in XX/XX/XXXX for not returning the car with a full gas tank. On XX/XX/XXXX, I submitted the documentation requested addressing the issue that XXXX is lying and changing its answers every time in an attempt to extort money from me. Although, at the beginning XXXX told me and Chase representatives that I rented the car in XXXX, in XX/XX/XXXX, XXXX has changed its response saying that the car had some scratches on the rear fender and bumper. I think it is very clear, the company is trying to get more money, lying and changing their answers in an illegal attempt to extort money from me. 
Once again, XXXX should have mentioned any damage to me after I returned the car in XXXX at the end of my trip in XXXX. In fact, the car had scratches when I rented the car in XX/XX/XXXX, as specified in the contract. I submitted pictures taken before renting the car on XXXX In the photos everybody can see that the scratches XXXX claims were added by me were on the car from the beginning. So, the original paperwork which I submitted to Chase was comprehensive and extensive. I included previous letters, emails capturing the conversation between XXXX and myself and pictures of the car at the time I rented the car which demonstrated that this is a fraudulent charge. If this had been an honest charge, XXXX would have mentioned any scratches/damage to me after I returned the car in XXXX at the end of my trip. They never did because the car was returned with a full gas tank in the same condition I rented the car. Chase Credit Card Services kept calling me and stating that this is a valid charge without providing any explanations. On XX/XX/XXXX I spoke with a Supervisor from Chase who asked me to submit again the documentation in writing. I mentioned to her, that the damage that is described by XXXX, it is captured in the contract I signed when I rented the car. So, until now, I submitted the documentation required multiple times via the Chase secure message. I am extremely concerned about this extortion on behalf of XXXX, and will pursue this matter further in court if necessary. I expect Chase to provide the protection you have promised me as a client in dealings with this disreputable company, who has twice attempted to submit inappropriate charges against my account.
