I recently did this with Charter as AT&T is also in our neighborhood. The person at Charter first tried to do an up-sell (which would have cost more money) and eventually came around to saying that they wouldn't offer the lower rate again. At which point I said, "I'm going to AT&T who will give me a better rate, cancel my service." Which resulted in a slightly rude interaction before they canceled my service. A week later AT&T internet was up and running.
It's was a very odd interaction given that Charter's fine print says that to qualify for the discount you have to not have subscribed to Charter's services for a mere 30 days[0]. Even with limited competition, now with MiFi hotspots a person could cancel their plan, do a pay-as-you-go MiFi hot spot for 30 days, and then resubscribe with the new rate. (Not sure if Comcast is the same.)

With our FIOS account I simply cancel service every year and and my wife sign up for new service in her name. Usualy we set this up to occur on the same day so practically no downtime in service. This has worked for 6 years now and while it feels ridiculous the savings are significant.
