JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Customer service / Customer relations California

I contacted Chase - customer service on -/-/2015 to pay off my credit card. I spoke with supervisor -, she gave me quote of $1400.00 and I asked her to close my account. I confirmed with her atleast twice about no further payments or charges. She said, this is the only amount I need to pay and the account was closed on -/-/15. I paid the amount in full right away. Today on -/-/2015 I received a new statement with new balance of $11.00. I called the customer service and spoke with another supervisor - -. He said, he saw the notes of my previous conversation with - on -/-/2015 and he even confirmed the pay off amount but he said, it could have been a mistake on - 's end or maybe she did n't understand me properly that 's why she gave me wrong quote, which is off by $11.00. But I have to pay the $11.00 because this charge is valid. If the employee ( S ) make a mistake, Chase should take responsibility of their under trained employees instead of making their customers pay for a valid mistake from Chase 's end. I feel like I have been defrauded and scammed by chase and I should not be paying the $11.00 of charge.
