This number is sending me the same message about a WalMart gift certificate. I NEVER shop at WalMart and will never shop there. This tells me Sprint has sold my phone number and is allowing a commercial venture I loathe to send me text messages, which I've told them specifically I do not want to receive. My phone is supposed to be incapable of receiving text messages, and now here's an add and Sprint is charging ME for the "pleasure." I want this to stop.
