Blocked from accessing customer service?

I have been trying to resolve one issue with Vodacom since 13 December 2024, but Vodacom has been giving me particularly poor customer service, so I have been calling them frequently to check on their progress with my query. On my last call, I was not let through to customer service, instead I was given an automated notification stating that I've been blocked from accessing customer service. Now, I can't even check whether Vodacom is working on my query. At what point does Vodacom customer service actually provide customer service your clients?
