Sudden Data Spike Unexplained

Unfortunately like many others on this forum I’m being scammed by Xfinity when it comes to unexplained data usage rates. 

For context I’ve only reached my 75% usage warning on the last day of the month a couple times. However today only 20 days into the month I received a 75% usage warning at 5am. This seemed pretty surprising since I’ve had very similar usage as previous months. 

I got even more surprised that at 10am only five hours later I got a 90% usage warning. At 2pm when I got a 100% usage warning I was shocked; I was either sleeping or out of the house from 5am-2pm. This seems literally impossible. 

As many on the forum have mentioned Xfinity is doing nothing to resolve this. I’ve been on a call for 45 minutes with no help at all. They just confirmed the usage emails I got; this is not helpful. They claim they don’t have the tools to investigate the data usage. They claim they have no way to check devices and data usage although somehow they can track it when it comes to charging us? They keep asking me to enumerate all devices ever connected and to use the app, neither of which are helpful. They are just giving impossible tasks to tire me out. 

Xfinity, I’m extremely disappointed in this predatory and monopolistic behavior. This is not a proper way to treat consumers. We will have to cancel services or file complaints with the proper authorities.
