Horrible service

I have been calling FNB continuously the entire day, either your systems are offline or you have *********** people who don't know what they doing. On Monday 8/1/2024 I called in requesting a paid up letter to be sent to me on my email for my Gold credit card. I was promised it would be done. I still have not received anything. I called multiple times today to only be told your system is offline. What the hell??? Couldn't even take my details to call me back when your systems are online. What kind of customer service??
