Telkom excessively bad service

I moved residence at the end of May and requested my ADSL line to be moved. It's always been an ADSL line. It took seven weeks for the line to be moved. I met with the technician while he was doing the installation to make sure everything is in order. It wasn't. His work order said he was supposed to install a voice line which was incorrect. He told me it's not a problem I should just call in to have it changed to ADSL. He also told me he can't understand why it took so long to have the line moved as they aren't busy at all. I immediately called in to have Telkom's mistake rectified. I was told that the installation job first has to be closed off before the upgrade to ADSL can be done. This was mid July. After waiting another week and still no action from Telkom I called in to find out what's happening and was told that there was an issue with closing off the job and it will be seen to by the following week. That didn't happen. I've been calling every week since then as nothing has been resolved yet and to date (22/08/2018) I still have no internet. Every time I call in I get told by the following week a technician will be around to correct the issue but this hasn't happened yet. I've tried speaking to a manager but every time I request to speak to a manager I'm told they are all in a meeting and he/she will call me back. They never do. For three months I've been paying in excess of R700 for internet I can't use and it seems Telkom can't be bothered to have it sorted.
