Data usage

I received a notification that I’ve used 90% of the 1.2TB included in my plan. Today is just March 7, 2022.  There is absolutely NO way I’ve used that much data in  7 days. I’ve been an Xfinity customer for 4 years and have never come remotely close to using this much data. I looked at my usage prior to February 2022, and I was averaging from 250GB to at the most 450GB. Nothing has changed in my household. It’s just my husband and I and we’re over the age of 55, we don’t stream, game or any of that .Has anyone else had this issue? I received an email stating I would be charged once I go over the 1.2TB. We were out of town for 2 weeks in February and my February usage showed we almost maxed out our usage. What is going on with Xfinity?
