Card Service Center

I get a blank blue screen after putting in my password. I have deleted the app and then downloaded this again. It still doesn't work. I have called them 5 times and they will always say they will send a ticket to tech. It has not worked for over a month now. USELESS APP/POOR SERVICE. Still doesn't work and it is over a month and countless phone calls promising to fix it. Their tech department is useless.
