YMMV. My method has been working well with Comcast. When it's renewal time, I call and ask for the retention department immediately (say "cancel" to the interactive voice response system). When the agent comes on the line, I say that my rate is going up and I just want to keep the same rate and same service. No threatening, no anger, no actual statement that I want to cancel. Just, "I want to keep the same service and the same rate. Can we do that?" It has worked for about five years so far. I switched to Comcast from Verizon DSL. With Vz, there was no negotiation, and besides, their service was actually terrible and I did want to cancel.
