Cingular has sent legal threats to Consumerist over Consumerist’s publication of Cingular’s customer service guidelines for determining how much of a discount to give to customers who threaten to leave. The information seems pretty harmless, but interesting, to me. There’s nothing there that helps you scam a better deal out of Cingular, just confirmation that some people might be getting a better deal than you. The discussion that follows is pretty good, too. Cingular avers that this is copyrighted material and is demanding that Consumerist take it down.
