Disappointment at Orlando international airport customer service. I had an account with Navy Federal Credit Union master card and I had . Retired fro US Army. My bank account with Credit Card was $12000 with zero amount own to NDCU. Dollar car rental said cant process the credit card. Called NFCU what's up what's up with the Master Card....Results was not the CREDIT CARD but the network system at the airport. After 25 ho25 hours of traveling it was very stressful. Overall, great service after all from DOLLAR car rental.
