worst customer support experience

customer service is shocking, was holding on for 15 minutes and got disconnected twice this morning. this is not the first time. i have taken to the social media pages at times to try get support after failing to get assistance over the phone even that gets me nowhere. the twitter page is just as useless as they only reply a day late. i would not renew my contract with MTN because of the service alone. Vodacom has a call me back service if you hold for too long or a web based chat service. so does Telkom mobile. Cell C responds to social media posts almost instantaneously. me and my wife use all 4 networks and MTN has by far the poorest customer care. Even the in store agents at Bedford centre agree with me after i had to drive to a store to get some sort of assistance
