Telkom poor customer service

I ordered a Telkom line and package in early January 2018. I received my order number and a week later my installation date for the 25th of January. On the day no one arrived to do the installation. I phoned Telkom on 10213 and was told that no technician was allocated to the call. When I phoned on the 26th of January I was informed that there was a problem that would be resolved in 48-72 hours then I would be contacted to schedule another appointment. This did not happen. On the 7th of February I phoned again and another appointment was made for 14 February. No one showed up for the installation on the day. I phoned Telkom 4 times that day and no one was able to help me. On the 15th of February I phoned again and asked to speak to a manager. I spoke to a person called Natie. He ensured me he would follow up and come back to me. I was not satisfied and asked who else I could contact. He gave me the escalation centre email address as well as his to send the complaint to and he again ensured me that he would follow up and give me feedback. The email address for the escalation centre he gave me was incorrect and I obtained the correct one from the Telkom website by talking online to a agent. I sent the email to both Natie and the escalation centre on the same day and received no response. On the 19th of February I sent another email to the escalation centre and again received no response. On the 19th of February I also phoned again and spoke to a person at the call centre called Webster who informed me that he has escalated the call again. On the 20th of February I phoned again and spoke to Sphesihle who assured me the situation will be resolved. On the 24th of February I phoned again and spoke to Precious Majola who informed me that there was a system problem and that both she and her supervisor will follow up and I will be contacted again with a installation date. Nothing happened. on the 26th of February I sent a follow up email to the escalation centre with no feedback as yet. Today 28 February I phoned again and spoke to Thulinisle who informed me she would ask her manager to escalate again. I asked her who her manager was and it was this Natie person again. I asked for his manager's details and was told his name was Thando. When I asked for his contact details I was put on hold and Natie was put on the phone. I had a discussion with him and told him I want his managers details. He said it was Thando Mantakhana and he gave me a email and telephone number. I proceeded to tel Natie that I was disappointed in his service as he assured me he would provide feedback. He became aggressive and kept on interrupting me which I find very very unprofessional. What type of manager is this???? I ended the call with him and proceeded to phone his manager - Thando. I got through to a Telkom switchboard and was told that they did not know a Thando person. I was then transferred to HR as maybe they could assist. This transferred call just rang for more than 5 minutes. I eventually gave up. How are you supposed to get service from this company if no one wants to help you?????
