Hey @Rob19 
If you added data top-ups they should be reflected on your Fido app and usage should be tracked in real-time.
Did you make any changes to your plan this cycle other than the top-ups? If so, it may affect what the app shows until a new bill cycle starts.
That said, which message did you receive? Was it a warning of 90% or 100% or was it a message that you were over by $50? Also, can you try calling *3337 from your Fido phone to see usage? Does it match what the app says or does it say that you have used up your data?
Let us know, we'll be more than happy to look into things.
