I hate to be that contrarian guy, but I repeatedly put off calling spectrum to cancel our TV subscription (we never ever used it) because it involved talking to an actual salesperson who clearly used all sort of tricks to get me to upgrade to stuff I don't need.

Note: I can upgrade plans on spectrum just fine, but cancellation or downgrades means talking on the phone.

Based on my anecdata, this technique works just fine for companies - either they can charge longer for things that are not used, and/or they get a chance to personally talk to a customer to upsell them.

I'd very much like to believe these technique does work against companies, but I don't see it.
