Dont spam my phone inbox please

My neighborhood computer shop is spamming my phone's inbox with SMS with offers ranging from ram to laptop deals. Too bad my Nokia N82 dont have the block incoming sms function. If not, i would have blocked the number this very instant. Hubby's Samsung has that feature. Damn, looks like Samsung has one useful feature afterall, lol. Shall i complain to Maxis over this. Yawnnnn.... like they'll do anything about it.
