No service

Telkom installed landline. We want to upgrade so that we can have adsl like all the house around us. My wife tried to get adsl from Cape Gate Telkom but they said we are not enabled to get adsl in our area...how is that possible if everyone around us has adsl in Ruwari Brackenfell??The new upgrade Telkom service box is less than 200m from our house. If check our number on the internet and it says our phone number is adsl enabled. We have been paying for line we cannot us. Can you please contact me and resolve our problem. Or come and remove your line and refund us for the installation.
