Data usage Alerts

Has anyone else experienced this? Our plan is only for 1 Gig Mobile Data. I have never exceeded that usage in a month. I had a Mobile Data Usage Alert set to send a text message when I reach 50% of that. I have only had that alert show up a few times include July 2025 so I know if was working as recently as last month. This morning, only about 10 days into my new billing period, I received an alert that I exceeded 1 Gig and I would be charged for another Gig. I never received the alert that I reached 50%! I have been home the whole time within range of my wifi. Wifi is working. I went to look and cannot find on xfinity app or on website how to check that the alert is still in place. I have reached out to xfinity customer service and iIt seems that there is an issue with that option because they now had to set it up for me (no longer in place without me removing it?!) because I could not find it with their help. Unfortunately, I am not satisfied with customer services response. "Turn off your data when not using it". Data should not be used in the home if wifi is on. Also, if there was an issue with my wifi and I had received the 50% usage alert, I would have investigated immediately since having that show up just a few days into a billing period is unheard of for me. I am told a ticket is opened but I have my doubts. 1. I feel I should not be charged for the over usage since their alert system stopped working and 2. they need to fix the alert system so I can adjust it and check to make sure it is still in place. Thank you.
