No installation

I app**** for a Telkom line 2-3 weeks ago. After filling in a form with a sales agent and getting no response for 2 weeks I app**** online and got a reference number (***) I am still waiting for any sort of contact from Telkom( a further 2 weeks later) regarding a timeframe when they will be coming in to install the line? There is no complaints department to call Telkom ( for obvious reasons) so I am at a loss what to do? I'm in desperate need to get a line installed and am quite confident that Telkom has forgotten about me.
