On the phone -- I could not drop it on the spot without talking to my wife ... plus lazy inertia. But, I do have telephone alternatives, which is more than I can say for Internet connectivity.
Verizon DSL is another weird story. I was their customer many years ago, getting around 5 Mbps down on a plan that promised up to 7. One day, they throttled it down to 1.5. When I complained, they told me that at my location with my geriatric wiring, I could only get 1.5. They were not willing to un-throttle it in spite of the fact that I had been getting 5 Mbps the day before. That is the day I became a TWC customer.
I just rechecked my Verizon DSL availability. They say I can get "high speed Internet enhanced" -- 1.1-3.0 Mbps down and 384 Kbps up.
In general, many people are like me -- busy and lazy -- and it takes something big like Verizon throttling my DSL or hearing that I was paying $40 for phone service to get them to get our attention.
