Data Use

[Services] How can I be liable for over usage if the tool is broke

Every time I visit my usage it always tells me the exact same thing:

"(USGP800) We are sorry, but we are unable to display your Internet usage at this time. Please try again later.. "

May get to see it once a week if lucky......

Has not been updated since 16 May, I have checked two reports and there is a disconnect in the two report, one (bar Chart) show 137 GB used as of 16 May, the other show 92.12 as of 21 May with 10 days left in billing cycle. So what gives AT&T?  I signed up for 6mps to use my streaming service and how I have to pay a penalty if I go over AT&T 150 GB limits, no U-Verse in my area............

So how do they expect to get away with billing me if I do go over?

Started on 14 May 2014.  Appears it might be time to find another more reliable ISP, with at least 250 GB data cap limits....AT&T is set at 150 and I do not have U-Verse and AT&T cannot tell when it will be available in my area..........
