I AM UTTERLY DISGUSTED

This is now the 3rd time I have had to complain on Hello Peter about this service provider that is just completely ignoring me. My last complaint MTN responded and they did nothing about what they said they were going to do. HOW CAN THEY OPERATE LIKE THIS. I call customer care hold for 5 minutes and get cut off every single time. I call the mentioned sales representative no response. The MD of our company emails the sales rep no response. I call the closest store to our office the representative promises she will help and get back to me, NO RESPONSE! I am honestly fed up. I have been waiting for my minutes, data and sms for this month. The same thing happened the month before and after I complained three times via Facebook and Hello peter I received everything. I hoped this would not happen again to me the following month, which it did. What am I supposed to do when nobody is responding to me. I cannot pay for my contract for the month of March when I have received nothing. MTN you should be ashamed of yourself. Your customer relationship management is disgusting as far as I am concerned and I only wish I was on Vodacom.
