50GB in 3 days would equate to around 500GB/month. What in the heck are you doing to eat that much data?!?!? Cloud services? 7 x 24 Netflix on HD? 150GB might not be a lot, but 500GB/month is well above the household usage norm/month, satellite internet or otherwise. You might want to look at why you are using so much data, perhaps there are ways you can conserve some.
