I"m going with malware infection or something as flat fish suggested. There IS something using data even when you're not "surfing". Turn of the wireless on all devices when not in use...this will stop things dead. You can selectively do this and find out which one is causing the issue also.
True but it doesn't sound like his son is playing xbox games online. It certainly will use a good chunk, at 60GB/mo. that's only a couple GB a day on average. Can't see that blowing it out for him, IMO.
You have to have something on that's using data while you think you're offline. I can't see even playing online games with friends using 15GB in just a couple days. I have also heard satellite is bad....it's the latencies that kill it. I had a coworker that was using a line of sight/direct WIFI from a provider. Basically they setup repeating towers using high power antennas to provide you with wireless service. It wasn't great but it was better than satellite but I don't recall what he was paying monthly either. I think that might be your only option. You can try to make sure all your wireless devices have their wifi turned off to be sure they're not using data when not in use.
No Mexican has soft hands....have you ever seen a Mexican's hands? Once that reach around starts your dick will be raw in about 3 strokes. Just sayin'.
She didn't get shit. Yup...keep an eye out the window. I'll be there soon. Nope. It'll take more than that to scare me away. I'm not going to ask for an address. If you wanted the sammich so bad you'd of sent it. You know I have balls. That tea baggin' I gave you proves that. I highly doubt it.
