Product: Credit card or prepaid card

XXXX   XXXX   XXXX   in late   XX/XX/XXXX   Preauth : Apparently no record of original transaction day ... ( wont let rep  XXXX    XX/XX/17     XXXX   XXXX    EST disputes go back for pending transactions past    XXXX   XXXX   2017 ) The transaction in the incorrect amount posted   XXXX   XXXX   2017 {$580.00} {$580 .00} for a 24 hr rental of a standard minivan. Original charge of {$82.00} approximately ( fees/taxes ).
Signature likely doesnt validate the {$500.00} charge.
Dispute :     XXXX   XXXX    , 2017 dispute filed with JPMorgan Chase   XXXX   XXXX   Card.
    XXXX   XXXX    , 2017 {$500.00} credit issued to me ( temporary ).
 XX/XX/XXXX ????? ( JPMorgan Chase )     XXXX   XXXX     2017 rebilled for full amount despite it obviously being a drastically incorrect amount even if you just  XXXX  to double check the prices.
Called several times before any charge posted   XX/XX/XXXX  because of abnormalities at the rental location. I was told I shouldnt be billed this a mount by both people at   XXXX   location in  XXXX ,  XXXX    XXXX   XXXX   XXXX   XXXX  ,  XXXX ,  XXXX   XXXX ,  XXXX  (  XXXX  ), and JPMorgan Chase. This is pretty obvious if you have any common sense whatsoever.
I spent numerous hours on the phone with all of these people, in addition to going into the branch on more than an occasion. Each time I was assured this would be resolved or it should have already been resolved favorably. The  XXXX  location manager even apparently failed to file the correct information with   XXXX   main office.
Regardless, it shouldnt be possible for somebody to fraudulently overbill you by {$500.00} just because they have your card details. This isnt even close to the first time this has happened with JPMorgan Chase   XXXX   XXXX   in just the previous year which is absurd. This is a basic premise of the cardholder protections in the card agreement. I expect a lot better from JPMorgan Chase especially for their   XXXX   XXXX   card. I 've helped correct JPM stock price in a number of situations where it was mispriced including during the   XXXX   XXXX   incident where the bank was dramatically oversold incorrectly to the point where it could have posed an actual threat to the bank if it had continue much longer. My comments had an immediate correlation with $  XXXX + of tangible value creation for the bank. Do you understand how many   XXXX   figure compensations JPMorgan pays people to *try* to create that type of value that was tangibly delivered not to mention the tangible cost of capital in the market for that type of value that can easily be independently documented? This is far from the first time theres been a problem like this with JPMorgan Chase which is genuinely terrifying. I was actually told explicitly that the same dispute resolution specialist that did something similar to this previously and that I have already filed a CFPB complaint regarding, handled both this and another dispute that were resolved dis-favorably with egregiously incorrect explanations as well as violations of the card holder agreement which is absolutely unacceptable. This seems almost like retaliation for literally just asking the bear minimum of whats in the contract and is obviously common sense. Despite all the value I 've help create for the bank, the risks I 've helped them mitigate, I 'm not asking for special treatment. All I want is equal treatment following the basic cardholder agreement, common sense and law. This situation really shouldnt be anything I should have to ask for, let alone waste my valuable time dealing with calling in repeatedly and visiting people in person. I expect far more from JPMorgan Chase as anyone should. This is terrifying and disappointing that I even have to file this just to have my rights respected.
