TELKOM LINE FAILURE

I live in Radiokop, Roodepoort and my landline/ADSL service is continually breaking down. Works for a couple of weeks then the line goes down for a few days whilst the fault is fixed. I need my ADSL line for business and have to resort to 3G connection when ADSL goes down thereby incurring extra cost. I've reached the point where I am considering Fibre option and cancelling my Telkom line. I need to talk with a senior person in Telkom to establish what is causing the continual breakdown but all one gets is a call centre option! This is not acceptable!
