Sprint never renewed my contract

[mulhiny]

So I went to Best Buy and renewed my contract and bought an HTC Snap for $29. When I got home I deactivated the Snap and reactivated my Touch Pro..Sold the Snap and bought my wife a new phone. Anyway, at the time my contract had been renewed for another 2 years. I called Sprint for an unrelated reason today and the rep tries to sell me a new phone and convince me to renew my contract. I just said no thanks and figured she must have made an error. Well, when I got home and checked the site, sure enough my contract has the old start date on it and is eligible for the $150 discount for upgrade. I bought this phone at Best Buy at least 2 months ago. Has anyone else had this happen? Anyone know why?
