Poor customer care MTN

Hi. My account has been suspended and I am told I have an outstanding balance of over R2000 because my account is on 30 days. My latest invoice does not reflect this and neither does the mtn app. As far as I am concerned my account is up to date. I am extremely irritated with the fact that I have been emailing mtn customer care since Friday last week with absolutely no response from them except to tell me my account is in arrears. NOT ONE of my emails are being answered. I cannot call because, low and behold, my phone does not phone out because it is suspended and I currently have no other way to communicate. As far as I am concerned, this is no way to treat a customer.
