WIFI fault not repaired after 2 weeks

I reported my WIFI down on 22/01/2018 however absolutely nothing has been done by Telkom to rectify the problem. Each time I call in, I get told that the problem would be solved by close of business that day - however my WIFI is still not working. Interesting to note that if I call my landline number (connected to my WIFI) someone else actually answers on the other side. Lady told me that her number has not been working from same date as my WIFI!!!! I am paying for something that I have no use of and someone else is working/calling on my account - how is this possible??
