Unusually high data usage

I am experiencing the same issue and was told to contact the Data Usage Escalations Team. Which is it? Customer Security Assurance or Data Usage Escalations??

Hey there, @joyce_g. It would be quite frustrating to have changed nothing on your end to your knowledge and see your data usage balloon. What troubleshooting steps have you taken from your end? Changing the WiFi password and disconnecting all of your devices and connecting them one at a time to see if data shoots up by adding a specific device is a great start to isolating the cause of the increase in data. Common occurrences are when massive files are not completing their download and constantly have to restart the process. A great example is a gaming system attempting to download a new game or update that gets stuck in the process and is constantly downloading until it's manually stopped. We see an increase in a lot of folk's data usage around the holidays due to more friends and family in the home visiting and logging into the network. 

Our Customer Security Assurance team is the one to typically handle cases outside of the norm with data-related issues, however, my previous tip to isolate the device/cause will go a long way to assist with finding the culprit with your increased data usage. 

Please also note that sending unsolicited direct messages to myself or any other user is a direct violation of our forum guidelines. You must first create a Public post requesting assistance, and once a Comcast verified employee responds and asks for a direct message to be sent, you can then proceed with doing so.
