Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Billing statement New York

My Barclasys JetBlue credit card is not counting credits ( returns ) that came in after statement closed but before payment for that statement is due against the total balance that is due. Every other bank and credit card that I have used ( all major banks and credit cards ) count the credit toward the current balance due. I feel like this is a bigger issue where they could be hitting customers with - and needs to be addressed by the bank.
