On XXXX XXXX, 2016, I called Barclays credit card account manager ; XXXX XXXX ( XXXX ), ID # XXXX to ask about the status of my case # XXXX. XXXX said that case # XXXX was not set up properly and he opens new case # XXXX, he promised me to resolve this matter before XXXX XXXX, 2016, which is the due date of my monthly payment to Barclays credit card. XXXX also advised me not to pay my minimum monthly payment to Barclays, which is due on XXXX XXXX, 2016, until this case is resolved. As of the date of this letter, I did n't hear anything from Barclays credit card. 
On XXXX XXXX, 2016, I made a payment to Barclays credit card for {$64.00} ( minimum payment due to Barclays credit card ). Since checks # XXXX was NEVER CASHED by XXXX credit card, Barclays never provide any proof of payment for check # XXXX, and all responses from Barclays account managers were fraudulent, I am asking Barclays credit card to give me a credit of {$6400.00} to my account # XXXX immediately. 
I strongly believe that this credit card company and Barclays Bank Delaware are in the business of defrauding customers and threat
