International plan minutes not updating or showing any minutes at all

Hello and i have the 300 International Plan and every few days check my phone account online as my minutes each cycle gets updated which is very hepful so I will not go over my 300 limit...but for the past 10-days to 2 weeks when I check minutes for this cycle month all I am seeing is blank spaces....same if I look at last months totals obvious ongoing glitch I am assuming..

Aug 27 will be the end of my current cycle and I need to know what my total minutes are as of now so I do not go over my 300 minutes allowed as i call my best friend who is in Germany everyday.....thanks in advance for any assistance.
