Never Ending Spam Messages

<p>Hi</p> <p>I have gotten to the point of extreme frustration with MTN. Everytime I buy airtime or data bundles, a flood of marketing messages comes flying through my phone. The worst part is that even when I haven't bought any airtime, countless marketing messages still come through and this has become very annoying.</p> <p> </p> <p>On Friday, I opted out of all the marketing messages that I could find and I received confirmation messages from MTN. Now today I've received the exact same messages I opted out of, from the EXACT SAME NUMBER! It hasn't even been a full week since I opted out. So am I supposed to opt out of receiving these messages every 3 days and keep getting charged every time? </p> <p> </p> <p>MTN, I don't want any marketing information. Should I have any need for it, I know how to get it. Please stop spamming me! </p>
