Navy Federal Credit Union [NFCU] review: Visa fraudulent charge

I received an email from NFCU today regarding fraudulent charges on my Visa account. I called NFCU CS at 1317hours & spent 5 mins with your A-I trying to speak to a live person. Your A-I is not responsive to requests for help. I was told that I would receive a call back in 12 mins. After waiting for almost an hour I called again at 1412hours and was told that that I would receive a call back in 8 mins. I received a call back at 1424hours, I could not hear the CSR & asked her to speak louder. She told me to call back later & hung up. I still need to resolve the fraudulent charges on my Visa account. Very disappointed this dismal level of CS.
