I take it all back

I'm on hold with Sprint PCS right now. Seems when I changed to a more expensive plan a year ago I unwittingly extended my service agreement with Sprint for another two years. In the words of Gomer Pyle, surprise, surprise, surprise. Now they want $150 to cancel my service. I can understand a service agreement when they're subsidizing the cost of a new phone, say. After all they need time to amortize the expense. But I've been a Sprint customer since March, 2000, paid list price for all my phones, and have been paying for one of their top tier service plans for the past year. There's no conceivable reason they should be able to extort $150 out of me for cancelling. Is there any other business that can charge you to stop service? I'm appealing my case to the Cancellation Department right now. (Must be a big department with customer service like this.) I'm going to swallow my pride and make nicey-nice. I hope I can get out of this absurd fee. (Update: They just waived it after noting that I work for TechTV. Hmmm.) The only bright side to this is that I don't have to apologize to Sprint on the show any more!
