Argo billing discrepancies

When I check my Billable usage for the previous month I see I burned around 260 GB. That’s pretty normal. Let’s say I burn 300 GB per month.

However, I constantly see 700+ GB charged for ARGO on my invoices.

I tried to discuss this with Billing support and all they did was confirm that the amount written on my invoices was correct - and to turn to Billable Usage stats for clarification.

Yet when I turn to Billable Usage the numbers are far off as I said. Usage numbers on the invoice are more than twice as big.

The Billing support didn’t understand that and kept saying their numbers were correct. Yet how and which ones if they differ so much?

What am I missing here?
