WHAT? First off Verizon is the LAST company you would want to go with and Comcast ties for last place right along side of Verizon.
If you would like a straight forward, honest answer to this question, here it is:
There isn't one. Period. (meaning, there isn't a "good phone/tv/internet bundle with reasonable and stable pricing")
Especially one that meets your criteria of "stable" pricing. That's a joke. Whether it is a penny or 2 penny's increase at the end of each month, it doesn't matter cause it is still an increase, thus unstable.
You should probably get a cable/internet bundle somewhere, maybe Bright House Networks, and use the Magic Jack for your phone - cause it is the exact SAME principal. If you bundle your phone, internet, and tv, you are still getting voice over IP service for your telephone which requires high speed internet access anyway, and at $19.99 per YEAR for phone service that includes long distance, well, at this very moment, NO ONE can beat that - no one.
