Vodafone's Manage Your Account Still Confused

When I now log in to see my account information, it appears as if all usage data is complete. But wait! What happens if I want to check my 3G Broadband traffic usage for the month so far?

I begin by requesting a total of all unbilled usage from the last 30 days. This gives me a figure of 659Mb, based on data collected from the 3rd of June to the 16th of June. That can't be right, since my current billing cycle commenced on the 22nd of May.

Next, I select all usage from the 22nd of May onwards. This gives me a figure of 1855Mb which seems a little excessive, so I add up usage logged on each individual day to get a total of 1230Mb. So how was the figure of 1855Mb arrived at?

To confuse matters even further, the cost column suggests that I am being charged for all usage over and above 1Gb even though usage beyond 1Gb but below 2Gb should be capped at $10. I trust that Vodafone will write off these charges at the end of the month, or they may just receive a rather rude phone call from me. Interestingly they have charged me for a total of roughly 260Mb which, added to the initial 1Gb allowance, would back up my belief that my total usage for the period is around the 1260Mb ballpark.

I really hope that Vodafone will improve the reliability and consistency of information provided by the Manage Your Account tool before the billing transition deadline on the 30th of June, or they will have a lot of flustered customers.
