Account Manager claimed 400% spike in traffic for my business account

I received this message on April 6th and I replied to it on April 8th.  I never heard back from the sender.  I had not been experiencing any problems, but I did due diligence anyway and checked my traffic and connection logs, etc...  How did the sender come up with 140G spiking to 600G?

Thanks

Nick

Subject: [removed per Community Guidelines] Spike in Comcast internet usage at -

Good Afternoon,

I hope that everyone is safe and healthy. I am reaching out to see if we can help you or the business during this stressful time in our country. Whether it's helping to transition you to work from home or making sure the business has updated data speeds to help work remotely, our new phone lines that allow you to display your business number while calling from a personal cell, and cyber security for when things get back to normal. Because times are currently uncertain we are now offering business month to month contracts with no commitment, You can upgrade now if you need it and downgrade in the future. Let me know how I can help.

The reason for this email is I work in Account Management at Comcast Business and your account is being flagged because you have had a spike in internet usage recently. You have been averaging 140 Gigs a month and last month your usage spiked to 600 Gigs. This means your current internet speed may no longer suit your business needs. Starting last October we retired a lot of our slower speeds, restructured our current internet speeds and deeply discounted our fastest speeds. Because you are a valued customer you are eligible for the best discounts we have. I’d like to take the time to review your account and the options that will best suit the needs of your business... I can be reached at [removed per Community Guidelines]

Best regards,

Hi Justin,
I would like to learn how you came up with those metrics for my line, and also how I can see them myself.  While there are links on the Comcast Business website that mention Comcast Business Connection Pro, that tool is either not longer available, or I do not have access to it. 

Thank you,
Nick
