ADSL Line, not installed for a month and a half

Absolutely no assistance from the sales team at Telkom regarding an installation that is pending for more than a month now. No one not even the manager can get a hold of the technicians. I have spoke to Ozzie, Nadia and Franklin and non of them were helpful. I have been put on hold everytime that I Called for more than 20mins and I have been following up almost everyday. This is for a business ADSL expected the service to be more efficient.
