The Worst customer service ever!!!!!!

My wife and I changed our contracts 2 months ago and from there it is a total mess. It seems like we are on 6 contracts now and are paying more than what our contract is stipulating. We are trying to sort this out by phone which is impossible. I have now paid almost R5000 more for the 2 months and nobody is contacting me or assisting me to try and sort it out. The customer service is absolutely appalling.
