Promise not kept, SHOCKING SERVICE EVER!!!

What a bad and shocking service from Telkom. I called on the 3rd of July to put in an application for the wifi router at my house. I spoke to Nadhira Khan who had been with me on the phone for approximately 60 minutes going through the process. She had confirmed that everything is concluded and that I should wait for the confirmation communication of this contract and the communication will be done within 48 hrs. I had waited and waited without any feedback from Telkom. Yesterday, 10th July, I’ve called to follow up, I was promised that someone will call me back for the feedback. I've waited for the call and there was still no call. I've called in again today and spoke to the sales advisor by the name of Malusi Sabelo, who gave me a shocking feedback...He said that my order had been cancelled because there is no adsl coverage. Why was this not advised initially?? You have waited my time being on the phone for a good 60 minutes. This ADSL was offered by the initial sales advisor (Nadhira) as I wanted the LTE. She had also confirmed that the installation will be done at my house within 14-21 days. Why DO YOU PROMISE something that you will never fulfil. If I had no called today to follow up, no one was going to call me back. Is this treating customer fairly??? I even want to cry because my kids were all excited about the promise that Telkom had made. I am very disappointed in your service...
