Cannot request to move my line

I have been trying to call your call centre every day this week to arrange to move my Telkom line to new premises. Every time I hang on for over 30 minutes waiting to get through to an agent. I checked your website to see if I could do this online - I cannot. I checked your app for the same thing - not possible.<br> <br> I am moving into the new premises this weekend. If I cannot request my line to be moved by then, then I will not be held liable for any phone calls or data usage after Saturday 05 September 2015.
