Verizon Wireless Verizon Wireless GOT me on DATA overages Nationwide Internet

 I entered into a 2 yr Wireless contract while in NYC, the first 6 months I used less than 1GB of data, I watch an occasional 2-3 min video , I don't play video games with friends over the net,my bill was around 70 to 80 dollars per month. I moved to California change my number to a local number for where I live doing the same things with my phone a Galaxy Edge 6 S+ and my bill is now incredibly high I was getting text alerts saying I am over my allowed data plan that month my bill said I used 18 GB of data f' n impossible no way, so for the next 3 months my data usage peaked at 25gb, so I opened a MetroPCS account the 60 dollar plan unlimited 4g data plan that first month I used less than 1gb will Verizon said I used 18gb I did not use that phone at all, then next 3 months while using Metro I have used about 2-3 GB of data--- Verizon needs to be taken to court for this data robbery if I went to Verizon and took a laptop I would get arrested so why are they able to blatenly steal money from hard working folks.
