DATA USAGE PROBLEM

And it's a problem I don't need. 

For the second time in the last 3-4 months I've had a huge data spike almost twice my normal usage.  Even more suspicious is the fact that my past months have also doubled in their reported usage, after the fact.  If I had gone over the data cap in those months then I'd have been charged for it.  So what are you going to do fix my data usage number for this month because there is no way i used I've used 61 gb of data per day in the last eight days, and the proof that something is wrong on your end is evident in my past months also increasing after those bills were already sent and paid.  I don't want to deal with this headache for the rest of the month and I don't pay for it, it's overpriced as it is,  how are you going fix it?   

Oh, and I don't have wi-fi so... don't suggest it.
