Insane data usage+slow network

Good Luck trying to understand Viasat.
We can only see being ripped off.
We have no choice but to use them out where we live.
Viasat is the only providers here. Believe me I’ve been looking!

We have been customers for 3 years and it only gets worse!
I have been keeping a ledger on the usage.
We have 150GB plan.
We only watch 1 hour of Swamp People in 6:30-7:30am. and
I turn the Viastat modem off / unplug it.
We was setting at 54.3GB and when I plunged the modem back
in we showed at 53.7.
Could someone tell me how we used GB’s when the modem
was OFF?
We can win for loosing here. And we all ways run out of our plan
and that is NO movie watching!
