Ummmm, filing a complaint with the FCC wont get you DSL any faster (or at all). That route is a waste of time.
I can not get DSL where I live either. They said I was out of range, and the customer base versus cost is not justifiable....
Also, just because you see a DSLAM, it doesn't mean that its serving your address or your area.
Do, you might as well stop complaining, it isn't going to help . ..
