Just a heads up for cable users.  Last weekend was the end of my data month, and I noticed a had a whole lot of data cap left and went downloading (10GB or so).  However, lo and behold on Monday, the first day of the new month, it said I downloaded 10GB in one hour (abour 11am-midday).

I raised this with Telstra Clear support who replied as follows:

"Thank you for contacting us and bringing this to our attention. There was an issue with the usage meter on the 19th and as you mentioned it failed to show data used on that day, rather it added this usage to day following. In your case this was to the next billing cycle and accrued on this months cap. Unfortunately we cant remove this usage, what I can do is give you a reference number and you can refer this to a customer service agent if you do get charged for over usage this month."

So if you have your billing period around this date, you might want to check you haven't been affected.

Cheers,
