Amex Credit Card Complaint

Amex Credit card department,

Delinquent account California

I am using my AME- for the company that I am working for, I will attached the email that I received from Finance Controller confirming this. I am behind on payment to AME- while I am waiting for the Reimbursement from the company. Amex has been calling my phone asking for my sons for payment. I am the primary card holder but they are reporting this delinquent to their credit reports. I am also attaching the statement confirming they have - transaction in 2015. They are only subsidiary card holders and should not be responsible for the delinquent of this account.
