Pathetic service from Telkom

My ADAL line has been done since the 07 October 2018 and they have told me that the line is faulty.I have phoned numerous times there after for them to send a technician out but each time a different answer is given. I am paying for the services and expect good service.I phoned in today again on the 10 October 2018 to ask to speak to a manager or supervisor and was told all of them are on training. What are they training for cos they are useless when attending to customers problems. Please assist.
