We cut the cord 2 or 3 years ago, switching to an Internet-only package at a drastically reduced rate (compared to what we were originally paying). We try to keep the costs to around $ 80/mth, while getting more than 25 Mbps (currently 60 Mbps).
Every year, they offer us a triple-play package (basic cable + 1 or 2 channel packs, VoIP phone service, bump up a tier in Internet) for 6 months at no additional cost. We take it, mainly for the bump in Internet speed, and then cancel everything back to Internet-only after the 6 months is up.
We've done that 3 times now. And every time we cancel, we let them know it's because of the ridiculous pricing they charge for cable packages. Hoping they'll eventually get the message that their cable costs are driving customers away
