Worst service ever!

I app**** for WiFi connection in April already. Karabo came to my house and advised me that would be connected in a weeks time but it's 7 months down the line but the is still no connection. I was August I was told that I need to make payment as they are prioritizing clients that have made payment. I made the payment and was advised that I would have connection in 3 days, we are in Nov now and I'm still waiting. I spoke to Fundiswa last week Thursday and she advised that the technicians would come over the weekend. I called her today and she advised me that the reason they didn't come is they were preparing for a function over the weekend. I specifically advised her that I work from home and need this connection to be sorted asap. I have been more than patient with these people. All I want now is to be refunded because I am utterly disgusted with their lack of service and no delivery!!!
