Not Receiving Low Data Notifications

<p>For the past 2 - 3 months I have been receiving NO SMSes warning me that my data is low. This is very convenient for Vodacom, because they just merrily blast through all your airtime too! I have been seriously considering switching service providers when my contract expires, after being with Vodacom for 13 years! Loyalty just gives you a gaping hole in your bank account, and I know in my circle of friends, I'm not the only one who has been complaining about Vodacom's billing issues that seem to have skyrocketed in the past few months! And please DO NOT suggest I download the app, I've read the reviews and will not do so until you sorted out those issues too.</p>
