Credit card or prepaid card — AMERICAN EXPRESS COMPANY (GA)

Credit card company isn't resolving a dispute about a purchase on your statement. I recently filed a chapter XXXX Bankruptcy on X/XX/2017. After American Express was informed of the filing they disputed all the charges that I have made 6 months leading up to the filing. These charges range from gas station purchases, dining, utilities etc. I called and tried to speak to AMEX about the issue and no one wants to assist or help me. This practice is unlawful and I need to know what to do in order to resolve this matter ASAP. My internet, cable, and cellphone have been disconnected and the accounts are pending disconnection. Can someone reach out to American Express on my behalf and have them retract these disputed charges that has been wrongfully executed.
