DISGUSTING MANAGEMENT OF ACCOUNTS

Since January 2015 I have had problems with my billing of my cell phone and after numerous visits to branches all over Durban and numerous emails (not resolved) cell calls (not resolved) In September this year my account finally was correct : I cannot believe it, my DECEMBER 2015 statement is now DOUBLE the amount I should be paying. I am a widow, pensioner and this anxiety and stress does nothing to help my health and well being. I tried sending an email to the ombudsman and the office of consumer council, NO JOY yet again. WHERE HAVE ALL THE EFFICIENT PEOPLE GONE?????? As for the management, when I asked to be put through to them, well they are the ROYALTY in MTN and by no means are customers able to either send them e-mails or converse with them. We pay for a service and should receive it and when it is not working, who do we turn to?????
