Constant problems with ADSL

Our Adsl / wifi at home constantly goes down. Telkom then sends technicians out weeks after logging the fault to fix the problem. The fault is found on the outside box in each instance. The most recent fault (reference 479CTK050416) has been logged on 5 April 2016. We have even phoned again after they allegedly corrected the problem (without any technician sent to our home) to advise that the fault still persists. The problem, according to the consultant on the phone, was then escalated and a new reference number given to us (849798). We have just returned from an extremely unpleasant experience at the Menlyn Telkom walk-in centre. Needless to say, nothing has been achieved. Our wifi is still down while we continue to pay for a service we do not receive. Telkom, please come and remove your ADSL line from my home with immediate effect. I never want to deal with Telkom ever again.
