Appalling service by Vodacom Technical Department

My fibre line went down on the 30th September. I was told by Vodacom that it is not their wifi but the fibre supp**** by Vumatel. As Vodacom is my ISP they were supposed to log a call on my behalf with Vumatel to come come a fix the fibre, to date Im still waiting i have been phoning Vodacom and been given a run-around by their Technical Department. this has affected my business as I work from home.
