Poor service from Telkom and openserve

I app**** online for a Home Unlimited (adsl) on 17 August 2018. I received a call the same day, completed my details and my order was placed. The order was only activated 21 August but nonetheless. I was advised there is a 7-14 day lead time in which I will be contacted by a technician to arrange a date and time to install. I received a call 27 August 2018 from open serve to arrange the installation. We set a date for 4 September 2018 at 12:30. On the day of installation I had someone available to let the technicians in but nobody arrived and I receive zero communication wrt why they didn't show up. I contacted Telkom on 5 September to complain and find out what had happened. The technician explained they cannot install on rainy days. I was then asked if I can be available Thursday morning 6 September. I agree ( even though I have a day job) and later that same day I receive a call saying the technician has no stock of modems. He did not call. I then proceed to call him and he says that he still hasn't received any stock. So essentially, I have till wait until thy kingdom come for telkom to have my adsl installed. I complained via Facebook but got no reply. I refuse to pay for a service I haven't begun using regardless of when it was registered in my name. If my installation has not happened by this weekend I will proceed to cancel the transaction. This is unacceptable service!!
