Hard to imagine that little video ad uses $50 in data. Maybe you have a trojan on your computer. Otherwise, use the picker tool in ad blocker.
I get my first 15 GB of data for $50 monthly. If I require more data it's $20 for every 3 GB that I add. That little ad will go through 3GB in a day or less. And it does this even though I don't ever see the ad.
