bad custormer service and lying and not sorting out problems

My partners Telkom line is not working from Sunday 10.12.17 he phoned Telkom and he was given this ref number ********** 29 and ********** 30 as he was querying two lines. He requested me to phone again on Tuesday 12.12.17 and I was told that they are busy sorting out the line and that the technician will phone him when they get to his place. He was then sent an sms saying the line is fixed which was not true. I phoned again on his behalf and I was given this ref number 947crk121217 and I was told they will speed up the process and send a technician again and still nothing. Phoned again yesterday and I was told the same story that they will speed up the process, till today 14.14.17 no one has came. I find the service terrible, he's using his line for his business as well, he has app**** for work, he has to send out emails, he's got wifi which is not working because people cant do their work properly. He is paying his account on a monthly basis. It really bad service and it is unacceptable, and lying to the client it's even worse.
