Hope you are well.
Do you have any existing line with us or telkom?
If not the first thing i would say that needs to be done would be to contact telkom to find out if your area supports adsl.
If your area can get adsl then you will have to get the voice line installed with telkom first.
Unfortunate you need a voice line first before an adsl line can be installed.
Omce this portion is complete you can then decide where and who you want your adsl line to be managed with.
