Promised fibre installation, no action after months

I am an existing Telkom ADSL customer. Approximately 2 months ago, I received an unsolicited phone call from Telkom's Sales department, informing me that there was fibre in my area, and that I could upgrade from ADSL to fibre. I went through the entire online application process, and was promised that a) my monthly subscription would be reduced, and b) that a technician would contact me to come and install a new router.

Needless to say, this didn't happen. Repeated attempts to contact Telkom have proved fruitless. I phoned the 10213 number, and then was told I selected the "wrong options" (no, I did NOT.) I attempted to use the Telkom web site, but no response to my emails.
