Internet data usage is unusually high

I have been an xfinity internet and mobile customer for over 7 years. I have never paid attention to my internet data since I never exceeded the 1.2TB cap, until August this year. It suddenly doubled my July's usage of ~800 GB to over 1600 GB and reached 90% by the 22nd of Sept. There are no new devices added to my network recently and have been using the internet same as always (no gaming etc.). I started to monitor my internet data usage with my wifi router and compared it with the xfinity meter. I found the xfinity meter number is shockingly bloated. For instance, on 9/28, my router shows <3 GB usage (I turned off modem for most of the day to save the data usage) but a live xfinity agent told me I used over 9GB for the same period, he admitted there is error on their meter, and opened an investigation.

This data overage has caused us a lot inconvenience and my family was forced to use more mobile data and got data overage mobile bill too. I hope xfinity can provide a clear explanation and solution.
P.S. We have no need or interest in the unlimited data plan based on our normal use.

Thank you very much for reaching out to us here @user_b778a1. I can understand the inconvenience of those data use issues. You can always reach the customer security team at https://internetsecurity.xfinity.com/help/report-abuse/ to check on and dispute any data usage issues.

I also am having an unexplained, huge increase in data usage.  We typically use no more than 15GB per month.  So far in October (2023) we have used 36GB.  I tried to contact a human at Xfinity to discuss, which, apparently, is impossible to achieve.  I am ready to cancel my service.

I too have experienced excessive data usage, double of what i traditionally have used. The spike occurred over last Labor Day weekend when xfinity in fact was out of service for over 24 hours. I heard different stories as to why they were down but nothing concrete. We were out of the country for 2 weeks in September yet our data usage still was high, spiking again using almost 800 gB in 2 days which was our usual usage for ONE month. The first 3 days of Oct it showed usage of over 1 Tb so i called xfinity. After a lengthy discussion I decided to convert to an unlimited plan but had to sacrifice some services to keep my monthly charge the same or less. I am not happy about this and will be exploring alternative services. Ironically the usage during Nov has been what I typically have used. Ie 500-750 Gb/month.

@user_o50iwq At this time data usage is verified by an independent, third-party auditor. The best course of action, in this case, would actually be to report this to our Customer Security Assurance. You can contact them by following this link: https://internetsecurity.xfinity.com/help/report-abuse/ or by calling CSA Toll-Free Number: 1-888-565-4329.
