In rural New York, US, I had the "pleasure" of dealing with Time Warner Cable (now Spectrum) as pretty much our only provider. We wanted basic TV and internet access, each were priced relatively high on their own but cheap as a "triple play" package when phone was included. I think our overall bill was $70/mo for the first year. After the 12 months, our bill went to just shy of $250/mo (promotion ended). We ended up only really using the internet with streaming services so I called them up to cut back exclusively to their internet dropping phone and TV.

This was the most PAINFUL phone call I've had in a long time that literally resulted in me begging them to remove these services after they made at least a dozen or two "what if we do this..." offers. Since that day we've never thought twice to getting TV again (or phone) and have strictly stuck to internet. I'd say weekly I get a new offer mailed to me but it goes straight into the trash.

It's all to apparent they make their promotional packages sweet enough that most people will sign up for them. Once the promotion ends you're stuck with all the "bells and whistles" at an incredibly high price. I believe they intentionally make their downgrade processes as painful as possible so most people just deal with the payment. For example you can easily increase your channel lineup/internet speeds online but you have to call to downgrade anything...
