Data bundles , airtime and sms not topped up

<br> I have contract with Mtn on Top package , my account gets is credited with data , airtime and sms's on the 12th of every month and each time it's done I would get an sms notification . This month of May the 12th I received an sms as usual that Mtn account has been topped up with 300MG , 100 airtime and sms but to date I have not received anything in my phone . I called the call centre for the whole of last week and have been given different stories, firstly when you call that 808 number you'll be on hold for over 45 minutes before you get to speak to the agent. I was told it shows on their system that my account has been topped and that it could just be network issues I should reboot my phone which I did , then when I called again I was told it was a general provision problem and that that customers have been advised and that it will be sorted soon the technical department is working on it , it has since not been sorted until today that has not been sorted but the debit order has been taken , so it's ok for me to pay MTN but I cannot get what I'm paying for ,instead I got an sms that my usage data has been changed to R3856.00 I don't know what that means.<br>
