Telkom just doesn't care

I've been trying since the beginning of April to move my line from Gauteng to Herm****. On several occassions have I called Telkom and in each instance I've had to wait over an hour to speak to anyone. They've promised me two dates for my ADSL installation and they just never pitch up. No communication at all they just don't care. I work from home and cannot go without a line which I've expressed to them on several occasions. All I get is a load of empty promises.
