Worst service ever!!

This is the worst service I have ever had!! I have been without internet since Thursday 25 August 2022, in the evening. I reported it to 3 different people on the Friday the 26th. Only the 3rd person actually asked more questions and had me reboot the router. I was told it was a Vumatel problem. the Vumatel technician arrived on Sunday morning, checked everything, all fine. He phoned into the office who checked the line and said that the router's IP address was expiring. I phoned Vodacom again twice on Sunday regarding the IP address. I phoned again on Monday. At least this person kept phoning me back throughout the day to report on the status. The IP address was changed, but the router now needed to be configured. By 18:40 this still hadn't been done. I phoned this morning again ( 20 Sept). This person now says it's a Vumatel problem. I am seriously frustrated as I work from home and have had to use my phone as a hotspot. I have already gone through a couple of hundred rands worth of data, not to mention the slow speed. Unfortunately I am stuck with Vodacom as they did the installation. If I want to change because of bad service I have to pay the thousands for the installation.
