Missing airtime

I would like to share my experience with other MTN subscribers / pre-paid clients. My wife and I check our balances (pre-paid) before going to bed and again the following morning. Last Thursday I had a balance of about R50.30. My wife's balance was R15.00. The next day my balance was R27 odd cents and my wife's balance was NIL. No unnecessary back-round apps running. This has happened on previous occasions but not on this scale.<br> <br> I believe that they are trying to maintain their profit margins through these actions and have now started using my Cell C phone more often, thereby reducing support to MTN.<br> <br> Please monitor your accounts.
