Unsolicited text messages at 7am and midnight

<p>Almost every day I am woken up by messages from Vodacom about not having an active data bundle, despite the fact that I sent an unsubscribe request over 4 *months* ago.</p> <p> </p> <p>I am not interested in these messages (in fact, I'm not interested in *any* marketing communication), especially since these bundles usually expire in about 3 seconds, and I really don't use much mobile data.</p> <p> </p> <p>Since sending my first e-mail to "customer care" back in mid December, I have recieved more than one phone call regarding the matter, but it's just empty promises.</p> <p> </p> <p>Why is this so difficult??? Perhaps it's time to move my business elsewhere.</p>
