Fault not resolved after 45 days - 360CRZ310715

My Telkom line says that the number does not exist when I call it. I have logged the call around the 31st July 2015, I have made numerous calls to the call centre with no assistance or feedback. I eventually spoke to a Team Leader Thando Dlamini on the 2nd September 2015 to escalate the matter, he was supposed to get back to me by the end of business 2nd September 2015 but he did not and has not yet responded to my e-mails about the query. I am now waiting on the line for 70 minutes so far for his manager Martin Chetty and have no response as yet. I have paid my bill monthly for a service that I do not receive. They have now cut the call, what do I do now???
