Pathetic service.

We recently moved into another place and wanted to move our line. After numerous times of not getting through we managed to change the adres but when we got an sms the adress was still the old one. We changed it again but the adress stayed wrong. Eventually we cancelled that line and opened a new account. We were sent an sms today that someone is on their way to install our line. Someone phoned saying they are on their way, I then received a phone call 30min after the call saying we won't be helped today because they have no one to put the line in for us as everyone is busy. We have been having trouble with telkom for over a month now and i am quite frankly fed up with this lack of service. This is very unprofessional. I demand the service that we were promised. You cannot do this to customers.
