Mad a huge mistake entrusting Vodacom with my Fiber Internet

I app**** for Vodacom Fiber in February 2019, the fiber installation was done on the 19 February 2019, I cancelled with my current SP and their services stopped at the end of February 2019, I had to contact Vodacom Fiber Sales department at the end of March as the interim LTE access modem and router was not delivered as promised, I received the interim access modem and router on the 2nd March 2019, I called Vodacom's Fiber support line on the 13th March 2019 to inquire as to the progress of the fiber install as the fiber installation was done in February and this is where everything went sideways, on the 14th March 2019 the interim access was cancelled even though the fiber is not working, I have without internet since Thursday last week, my cloud services are done, I cannot etc, the only support you get from the Vodacom support line is that the issue has been escalated as the modem needs to be configured, it seems Vodacom is ill prepared to offer this service, have I made a huge mistake here, I called the Vodacom support center this morning ( and asked to speak to a supervisor ( ********** 4) and was told that supervisor are only available after 9 and i left my number for one to call me, its now 9h17 and I am yet to here from one, I am at my wits end what do I do?
