No joy

<p>I have a top up contract phone with mtn so i recieve R500 airtime monthly and normally the balance its carried over to the follow month. So yesterday i wanted to make a call and i was told of insufficient airtime then i checked my balance and it showed R208. I was busy at work then later i attempt to make another call, i was told that airtime was insufficient with 00 balance . I contacted mtn and explained my story. Im frustrated because im scared to top up and i need to make call. Yesterday they gave me ref number ********** 44. I requested that they make it urgent but when i call this morning i was told to wait another 24hrs. When they want their money month end they dont wait 24hrs but when ptoblems arraise i have to wait</p>
