Well, that was fast. It took me about six hours before I cancelled that Verizon DSL service I'd signed up for. I needed technical support because of an issue related the wiring in the building (my apartment is wired up, but isn't properly connected to the local loop) and instead of getting someone to help I was merely passed from person to person. After the EIGHTH person passed the buck, I told them to connect me to someone who could cancel my service. After that person transferred me to someone who could actually do that -- no joke! -- I cancelled. One interesting factoid: if you tell them you're going to cancel, even if you've only been a customer for a few hours, they'll offer you two months of free service (obviously I didn't bite).
