Appalling lack of service and no feedback

I’ve opened a Fibre contract with Openserve Telkom (through Vodacom) on 26th November 2021. I had a technician come to install the fibre but wasn’t able to due to “the black box” missing on the telephone line. He reported it and assured me it would be done before Christmas. I called and notified Vodacom multiple times to find out when my fibre would be installed and all they did was say they’ve escalated the matter to Openserve but cannot tell me when I will be helped. Between myself and Vodacom employees, we’ve escalated the matter approximately 5-6 times over about a 3 week period with no results. There has been no feedback from Openserve or Telkom. I have called Telkom myself and spoke to the sales department for Openserve and they did not help me either. I’ve had to use other sources of data for internet to work from home and use up much of my airtime to make calls and try get a resolution to this lack or service and feedback. Who is supposed to pay for all that? And over the Holiday season, during which I still work, saving rhino and other endangered wildlife species from poaching. Without internet, I cannot communicate efficiently and save lives. According to Vodacom, Openserve is not responding to them either or providing any resolution despite all the attempts to escalate the matter. Out of frustration and loss of hope, I am forced to cancel the contract that has provided nothing but frustration, stress and NO SERVICE.
