@magdaleenmeyer Though it does not answer the question directly, I'd suggest going with alternatives to the large incumbents for things like mobility and Internet. I played the game of threatening to leave without a match for years and came to the realization I'd rather not give them one cent if it means begging.
For example, in Metro Vancouver you can go with Telus or Rogers (formerly Shaw) for Internet and get locked in for 2+ years to get an OK rate that is guaranteed to go up if you roll the term over, or go with Novus to get a better rate with no contract. Which options you have, specifically, will vary, but in major urban centres there are almost always alternatives to the big players that don't reward loyalty with rate holds, but rather rate hikes.
