Vodacom Apple Watch Cellular service not working

The apple watch cellular saga continues with Vodacom. If you are thinking on using them...DON'T! I purchased an Apple Watch cellular last year and what an absolute nightmare it was getting it activated with Vodacom. This year, my watch was replaced and I activated the cellular service again through the Watch app on the iPhone. Everything appeared to be in working order. I was charged for the activation and have been paying a monthly fee for the OneNumber service. Unfortunately, the service has mysteriously stopped working. I have tried emailing Vodacom - no reply. Then I tried the Tobi chatbot - useless. Then I spoke to a consultant - equally as clueless. She kept telling me to activate the service that is already activated! I am still being charged for a service that does not work. The iPhone Watch app shows the Vodacom plan as "not in use". The watch, when tapping the icon to activate mobile data, shows a black screen. Turning everything on and off DOES NOT WORK VODACOM. Nobody seems to know what the hell is happening. I delayed upgrading with Vodacom for years but eventually succumbed and boy do I regret it. I cannot seem to get any competent assistance with this.
