MTN Billing Issues and Lack of Customer Care

So, around Middle June I made a R400 payment and end of June I made another R400 payment as I get paid fortnightly. My bill should be between R710 & R790. After the first R400 payment, I get an SMS saying there is approx R93.00 outstanding, no big deal, I'm still in the month and know I will be paying the other R400 end of the month. Last day of June I get a notification that payment of the R93.00 has to be paid in 2 days or the line will be suspended. I paid R400 the next morning. They suspended the line an hour after I paid ( and a full day earlier than stated in the message ). 2 days later I get a notification that my payment was received, then again 2 days after that, the same message asking for the R93.00. Line is still suspended. I tried calling 808, online assistance, emailed customer care and sent a message on Facebook and there is no answer or response. Please can someone from accounts get in touch with me ASAP ?
