I hate Sprint with a passion. I was a customer for 15 years until leaving for Verizon last month. They extend your contract automatically for ANY service change. They made a mistake on my account, initially refused to credit my account AND extended my contract for another year. I flipped out and canceled (they waived the fee) Consumerist has some good tips about getting things done at Sprint: http://preview.tinyurl.com/yuo2lk
all, though.
