Product: Credit card

I rented a car for one day from XXXX for a vacation in XXXX. I pre-paid for the rental on XXXX 's website using my Marriott Rewards Chase credit card. 
During my vacation, I picked up my car as planned in XXXX, XXXX on XX/XX/XXXX, and was on my way to XXXX to go to the airport when I had a flat tire on the highway. I pulled over immediately upon being alerted by another driver. After failing to find any spare tire, I called the XXXX number provided on my rental agreement. The XXXX representative told me there is no spare tire in the Galaxy minivan that had and that she is sending a tow truck. The tow truck towed the car to a service station used by XXXX, where I was told that they could n't find a replacement car so I had to take a taxi to the airport, for which I paid XXXX XXXX. After spending at least XXXX hours with the XXXX rep at their counter at the airport in XXXX, he was able to locate the car and validate my story. He instructed me that everything will be taken care of. 
Upon returning XXXX, I was disturbed to see a charge of {$730.00} on my credit card from " XXXX XXXX XXXX ''. I disputed the charge and called Chase to explain. After several back and forths, a manager at Chase agreed to remove the charge and " handle it with XXXX ''. The charge was removed and I did n't see it on my Chase credit card bill for XX/XX/XXXX-XX/XX/XXXX. Then in XX/XX/XXXX, it suddenly re-appeared and I received a letter explaining that upon further investigation, they determined that the XXXX XXXX charge was legitimate. I again called Chase and talked to a supervisor to explain what happened and why the charge is not acceptable. I explained to him that I considered what XXXX XXXX is doing fraud because they are the ones who instructed me to do what I did and I followed exactly their instructions after they assured me that this is their standard policy. They then charge me for exorbitant amounts of money and refuse to pay my taxi ride which they arranged for me. In short, my XXXX day car rental was going to wind up costing me in excess of {$1300.00}!!! I told the Chase manager that this is exactly what I expect my credit card company to protect me against because they are much more capable to counter XXXX XXXX 's fraudulent practices than a single consumer like myself. 
I have been a customer of Chase for over XXXX years ; I use XXXX Chase credit cards for a lot of my business and personal transactions and my average balance is around {$6000.00} each month, which I pay on time like clockwork. I have never gone over my limit and I have never had a dispute of this nature in my long history with Chase. That 's why I was enraged that instead of fighting on my behalf, Chase simply threw in the towel and demanded that I pay the {$730.00} charge. I did pay my bill because I had no choise, but decided to close all my Chase accounts because I concluded that they are a terrible bank that refuses to protect their customers, even though the amount in dispute is trivial compared to the XXXX of XXXX of dollars that I have channeled through them with my transactions over XXXX years. 
I feel that Chase acted in an unethical and bullying way and is penalizing me because I do pay all my bills on time and they do n't make enough late fees and charges from me.
