Data Overages for first time with no change in usage. What's up?

Question

I see there are numerous posts about unexplained data overages. I think Verizon is manipulating the data changes somehow.  I have always used about 2 gig a month, but had a 4gig plan. Never went over. Then one morning I had a text that I had used 75% of my date. Somewhat surprised, but I drove to work, none of my devices on. When I turned on my phone it said I had used 90% and within minutes said I had exceeded my data. I called Verizon with a lot of questions as how could that have happened. I was not given a response that made any sense but was told they would increase my data plan to 6gig for no additional charge.  I agreed. Now at the end of this month the same thing happened. I went over my 6 gig with no changes in my usage. I do not stream music or watch videos, etc. No way I could have used that much. It showed I used 1.6 gig in one day, that's what I used to use for a month. Something is not right. What agency governs cell phone companies. We all need to report this.

It all comes down to those "pre-installed apps" and their updates that just won't stop downloading.
today, I realized that my phone was running kinda slow, so I went into the application manager and started deleting apps, and their updates. It took me a good hour to get all the useless ones out of the way, when I accidentally deleted all my contacts. Since my contacts was really the only thing I cared about, and now they're gone, I decided to go ahead and do the factory reset. Why not? So I started all over again like it was a new galaxy s5. My contacts came back no problem, and so didn't all those  useless apps I deleted, so on my way back to the app manager to start deleting them again... I checked my data usage and how many gigs I had just freed for myself... a whole 8.57G out of 16G now freed up! nice right? Yea, then I see that little exclamation point in the top left corner, it said 30 apps have been upgraded, and there was nothing I could do to stop this, I don't want to go through all those apps and updates for a 3rd time. I thought,  how much data is that gonna use? Turns out... 2.74Gs in 20 seconds and that was olny just 20apps, out of what 130 apps? That are being updated regularly everyday
Now I'm starting g to make sense of it now... my parents knew we were being had, for awhile now, just didn't know how. We've been talked into getting a 4G family data plan, charged over 900.00$ verizon bill, charged for data overages where we too don't use our phones for anything other than phone calls, or looking up something on the net. No music, no movies, none of that fun stuff. I see that in a matter of 20 seconds our data limit of 3G is just 1/4 away from gone, and that's just, what? 1 or 2 unwanted updates away from another overage charge? So I try to stop these updates by selecting in the Google play settings "do not update apps" but that simply doesn't work. It seems by simply connecting to WI-FI will negate my command.. and the updates keep coming. Only by shutting off both mobile data and WIFI seems to stop the updates... temporarily. It's hard to explain but it looks like verizon is using Google play app updates to max out data, and verizon is charging us for overages 2 and 3 times a month! They manipulate the data to make money, Stealing, and we're not the only ones, you caught them too ^^^. This is criminal, and something does indeed need to be reported to a proper governing body above verizon.
This has been going on in my family unnoticed for years, until now.
Resulting in ridiculous bills, coupled with false overage charges. Causing nothing but heartache and stress for my family, but we still pay... God I don't know why. But we do, and they just keep Taking.
I found out their heartless corporate bullying tactics against the little people, and you did too ^^^ they just keep throwing new "plans" and "6 more gigs" at us.
They sneak these updates right under our noses, blow up our data and threaten us to pay, or else we'll be blackballed from cable/Internet everywhere.
this is nothing else but criminal, rigging the game.
We don't want more gigs, we want our money and out mental health back!
