Anyone else see that MyVerizon Data Totals Do Not Match Detail?

Question

We have a 6 GB  share everything plan for 5 devices.  I used the My Verizon app on the phone before I went to bed last night  to look everyone's total data usage,  and it tells me  halfway into my billing cycle, that wer are at 2.5 gigs. All well and good.  But then not an hour later I am awaked by the beep of an incoming ttext message and  email from Verizon that says our usage is now 75% of  our allowance.  WHAT?
Next AM I log into My Verzon on the PC, not the phone.. We are still at 2.5 gigs according to the grand total on the report.  I then go into each line to see who is using how much and at the bottom,  I select, download to spreadsheet, for each line. . I now have detailed,  date and minute info on how many kilobytes or megabytes were used for the billing period to date  I add them all up for each line and sum all the lines together and whaddaya know, our total usage is 3.9 gigs.  Thats 64% of  allocation, not 75%, but its sure more than 2.5 gigs,
I place the call into customer service, how come  the text and email warnings do not match how much data you show in the My Verizon app or in the detailed spreadsheets of every single data transaction on each of our phones when placed into a spreadsheet. Initially the rep looked at the same general report I did and assured me my usage was only 2.5 gigs.  So why the warnings and why does the detail show something different from the grand totals in the app?
Was placed on hold while they did research.  After a bit, the rep came back and said they don't know why the totals do not match, Verizon does think there may be a glitch with the warnings that go out,  however they are going to do some research and will call me back in four days.   Well, I figured this was a bigger problem on their side then one phone call would solve, so no suprise there.  The rep also opined that the detailed usage spreadsheets probably reflects non billable usage, that is, usage will on WIFI. Incredulous, I asked, does this mean Verizon is tracking how much data I use while I am on WIFI and not even on their network? (Am I and my family being spied on?)  Not sure, was the answer, they will get back to me on that one.
I look forward to the promised call. 
However, I am very concerned that with being on a limited data plan and nobody has any real idea how much data is used,  the tools furnished to us to measure how much we consume may be unreliable and totally inaccurate.  We will see what they say.  Anyone else?

Answer 1

The app isn't always up to date. Neither is the website it will tell you the last time they have for each phone usage. We have multiple smartphones never had an issue will data billing being wrong. No Verizon doesn't count wi-fi usage. No Verizon is not spying on you. Verizon couldn't care less how many "lol cats" pictures you look at everyday. The data meter on my phone( not the Verizon app the actual data app on my Android phone ) matches what Verizon says I will say 97% or more.
