Who I have the same questioned this topic

I have been a Verizon customer for the last 5 years on a per paid on a old flip phone until about two months ago when I finally broke down and got smart phones for my family and put us on a plan. And so I am new to data and usage. But I was told if we went over our plans data Verizon charges high $ for it. So when we got close to our plans data being used up I upped our plans data. But what gets me upset is we didn't use it up last month so we Verizon took it away. I don't know where Verizon was companies morals are. But from where I come from when you buy something and someone takes it from you that's stealing. How do they get away with this. Could you imagine how much they have stolen from their customers? If you add it all together, I don't know about the laws where their from but the law here says that if you steal over a few thousand dollars it's a felony and you go to prison for it. If you added all the data that Verizon customers buy to have stolen back at the end of each month I'm sure it would be more then a felony amount. I'm  seriously considering changing cell phone providers due to this problem I see with Verizon.
