Still waiting for service

We are moving house on 19 March and need to change the address of our telkom line with ADSL. I called Telkom at the end of Feb and asked all the necessary questions. I was told to email [Email Removed] which I did on 1 March. I never received a response. I called again on 9 March and was told a different story by the call centre agent who booked a disconnection for 18 March and gave me a ref #: ***a. I informed her that it is imperative that a connection date is arranged asap, for as close to 19 March as possible as we use this line for business. She couldn't give me a connection date and told me that the disconnection needed to be done first and that a technician would get in touch. I called again today to confirm disconnection time for Friday and to enquire again about a connection date. This time the call centre agent gave me yet another story and said that the technicians are still evaluating the order and that the line won't be disconnected but she can't tell me when it will be connected. She said it usually takes 7 days and as you can see I first contacted Telkom on 1 March and it's been 7 days since my follow up call.
