Different info different consultants - no action

I have phoned the Telkom call centre numerous times. They keep putting me on hold because they need to speak to a manager. I have spoken to at least 5 different consultants over the last few weeks and they each gave me a different version of what I am supposed to do. The names that I managed to get before being put on hold are: Angel and Shabir. The other consultants mumbled so badly, I couldn't make out their names at all. I am tired of being put on hold for at least 20 minutes before I give up and put down the phone. The end result: I still don't have ADSL after 4 weeks of trying. I was promised that I would be contacted by a consultant. That was 2 weeks ago. No luck there either. It is the most frustrating thing, phoning a telecommunications company and there isn't even an automated voice telling you to 'please hold, a consultant is attending to your request'. It's just quiet..... My customers need to be able to call on the land line so have to phone from my cell phone. It's costing me a fortune to listen to silence.
