RIDICULOUS

I have been trying to contact the MTN customer service centre since yesterday. In total I have been on hold for over 2 hours over 4 different phone calls. My cell has been disconnected for no reason despite payment being made last week. I cannot even get through to speak to somebody to resolve my query. I cannot make / receive calls, sms'es etc.unless I am on Wi-Fi! This is nothing short of pathetic. Can somebody please call me to sort this out!
