I have Comcast and they just socked me with a $12 general increase, bringing my tab for basic cable and internet to $130 per month.
I went in person to pay my bill and I told the rep this would be the last month I'm paying and will be switching to Dish plus DSL for internet. Immediately he said, "Wait a minute, let me see if I can help you".
He offered me the same channels plus about 20 more, internet included for $69 per month for 6 months, at which time it would increase to $89 per month. He said also, "come back in in 6 months and I'll see what else I can do for you to keep that bill down".
I felt like some what of a dumb ass for not complaining sooner. It seems that with the hint that you might go elsewhere, their rates become negotiable.
I really did not want to switch to Dish and DSL but was prepared to do so.
I might pull that routine this week.
Be aware that you can probably only do that twice with Comcast. Then they’ll require you to sign a 2 year contract. Been there, done that. Ended up getting DirecTV after 2 consecutive months of price increases. When we went to turn in our Comcast equipment, there was a line out the door of people bringing their equipment back too.
