PNC Bank N.A. Bank Account Or Service Complaint

PNC Bank N.A. Bank account or service department,

Checking account Problems caused by my funds being low Delaware

My credit card erroneously debited my bank account ( PNC Bank ) for the entire card balance instead of the payment submitted. There were insufficient funds to cover the payment, which was - my bank balance. PNC Bank approved the charge, adding overdraft fees and leaving me $ - overdrawn, with my rent and bills STILL DUE. The credit card company, -, is refunding my account - but the transaction should have been declined by PNC Bank in the first place, because now I will have late payment charges for my rent and other bills since that process takes 5 days. This should never have occurred in the first place. The charge should have been declined for insufficient funds, leaving my bank balance intact.
