Data usage meter failure [Edited]

My normal data usage is 200-300GB per month. However for this month that usage has spiked to more than 1.2 TB (and is still growing). I called multiple customer support numbers and after finally reaching a human I was told to change my wifi name and password, which I immediately did after hard resetting my modem. I have not added any new devices or changed my usage patterns. But the meter still shows excessive data usage and now I'm over my monthly limit. I can't get anyone to help me resolve this issue.  Something is wrong with the meter and I need someone to address this issue. 

I've been talking to agents for multiple days - I keep getting transfered before any solution is found. I keep trying to escalate this issue. I've spoken to the CSA and tech support teams to no avail. 

I've seen multiple other forum posts of people have the same issue and xfinity employees saying it's known and they're trying to fix it, but no one follows up with a solution. They span from years old to just a few days ago.

Other people are having the same issue:
