Pathetic service

I have had a Telkom land line for years and I cancelled in July. On Monday I phoned to reconnect my landline and was told that a technician would be at my house this morning. I even received an SMS confirming this. Nobody has arrived, nobody has contacted me and I cannot afford to sit on my cell phone phoning Telkom to get answers. Whenever I phone I have to listen to the recording that Telkom is experiencing high call volumes (no matter what time I phone). When I eventually got through to someone she cut me off. I really am wondering if I should ever have reconnected my line.
