Hahahaha LOL.
I had a very similar experience. I called gulf telephone b/c my DSL was freaking out. I get a call back at work a week later from that same person telling me the problem is that I'm using my DSL too much. Then the guy asks me what I'm using it for. I tell him, “File Sharing, Web Surfing, that sort of thing.” I'm serious, the guy starts yelling at me over the phone telling me that I can't use my DSL for file sharing and blah blah blah. I thought he was going to stroke out, right there.
I matched his shouts with my own, which I'm a little sorry for doing - “You make the assumption I'm file sharing illegal stuff. I file share 3d models, graphics files, asp code, tutorials - legal stuff.”
I too, pay for a static. (Not for long, though.. =) ) Fortunately, I only have a single static so when the price raised, recently - I only paid an extra 10/mo. My take on the whole thing is - it's okay for them to charge you and supply a static so long as you don't actually use it for anything.
