As I tried to explain in the last post, disregard what you see in the screenshot called "data-plan-resume.png" - it is calculated for a different period.
On the other screenshot, you have chosen to view the cumulative bandwidth - meaning values for each day are added to the values of the previous day. This page is the one you should look at, but please focus on the bar for bandwidth at the top - there is one at the very top of the page, which is for all your apps in total, and there is also one for each app, listed below the totals. Please view the attached screenshot for guidance - notice the URL, yours should be similar (just the id should be your account id) to make sure you are in the right place, and the bar circled in red should show your bandwidth usage for the current billing period.
Once again, I want to assure you, the bandwidth and push notifications count quotas are monthly - they reset every month. If you think yours do not reset, we will investigate. But from the screenshot you sent I can see that the bandwidth used from the start of the billing period is about 20GB, which seems in accordance with your consumption.
I understand how the representation of some of these metrics can be confusing and we will consider improving them in the future.
