Unable to set up ADSL - no username & password

Good day, I subscribed for a Telkom ADSL in mid January, around the 12 or 13th of Jan. the technician installed the unit but told me I will receive an sms with a username and password to allow me to set it up. I have still not received the sms and I have tried calling the call centre and there is always no answer. I then sent an email and a lady from the call centre called me while I was at work and I asked her to please call me on the Monday afternoon when I arrive home...I am still waiting for the call. I have tried to call the call centre again but alas, no answer!<br> I will appreciate it if I can receive urgent assistance in this matter, otherwise I will be cancelling the ADSL. Telkom is so inaccessible and it is frustrating me as a customer, rather a helpless customer.
