First National Bank of Omaha Credit Card Complaint

First National Bank of Omaha Credit card department,

Billing disputes California

I attempted to file a graduation application during " no fee '' period but - computer system did not work, would not allow me to file. - charged me $50.00 for graduation fee, but then acknowledged in writing that I was not at fault because their computer system did n't work. Merchant now refuses refund. I disputed charge with card issuer First Bankcard, submitting copy of - fee schedule showing no fee due and the email acknowledging I was not at fault. The credit card person apparently either did n't read my letter or did n't understand simple -, and arbitrarily disallowed my dispute.
