Fed up with Telkom

I logged a dispute with Telkom in July and to date, the query has not been resolved. I moved to a new residence in June and subsequently requested my telkom services to be transferred to the new address. I also requested the line at the previous address to be canceled. However, the bill still showed that I was still being charged for subscription and usage of the line at the previous address. I immediately logged a dispute once I detected the incorrect billing. That was back in July and nothing has been done. My internet service has now been disconnected because I have not made a payment as I have been waiting for the adjustment that I was promised in July. Everytime I go the telkom to do a follow up, I'm asked to leave my contact details, someone will call me back. This has been going on since July. Telkom was very quick to disconnect my services, but not quick to address a 5month old query. Today I went again to the store in Westwood and was asked to call the billing department. Spoke to a consultant by the name of Sibongile who then put me through to Zolile her manager. Zolile was a special one because he was very understanding of how unacceptable this whole thing was and promised that he has personally asked his colleague to work on the dispute and it would be resolved by 1pm. Furthermore, he even gave his word that he would give me a call at 1pm to advise me of the resolution of the dispute. This all happened before 12pm. I left the shop and waited at the mall for 13:00. I even gave Zolile an allowance of 30.mins more but still no call came. I went back to the shop, where I called the billing department again. This was now 13:45. I spoke to Juanita who also tried to pull the "we will call you back" card on me but I wasn't having it so I requested to speak to a manager. By the way, Juanita spent a good 5mins arguing with me that there was no manager called Zolile in the billing department. So, after waiting for eternity because supervisors were on other calls, she said she would put me through to a manager called Thulisile, and subsequently abandoned the call. I was holding for no less than 20mins more and realized that nobody was going to return to that line. Call was probably muted for me to give up and hang up. I don't even know what to call telkom service at the moment. Telkom does not care about its customers, period.
