So last month I got a text stating I used 1.6gb of my data and if I go over 2gb that I would not receive my kickback. So I stopped using mobile data and made sure I stayed under 2gb. My Galaxy S20 showed I was under 2gb. The t-mobile app showed I was under as well under the usage page. So I thought I would receive my kickback. But I did not. The bill stated I went over and I would not get a kickback for that line. Whats strange is I never got a text saying I went over and that I would lot receive the kickback. Like I usually do if I go over. I checked my phone and app again and both said it was under 2gb. Except when I dug deeper and checked usage details in the app, it did show I was over 2gb. But why does that not match my phone or the app'd usage data section.
So fast forward to today. Again my phone shows 800mb of usage as seen below.
The app usage page matches what my phone says as seen below.
However under usage detail it says 1.49gb. What gives?
Another thing to add is that all of my 5 other lines. The usage detail page matches the usage page and the phone.
I honestly believe something is messed up on tmobile's back end system and calculating my usage incorrectly for my one line. Which is costing me extra money because I am not getting the kickback that I qualify for. Please help.

Your best bet is to contact Tmobile on one of their social media accounts using messenger.
