Unresolved eSIM Activation Issue on Apple Watch for Business Account

I purchased an Apple Watch with an eSIM in December 2022, and since then, I have been unable to activate the mobile service on my device. My mobile keeps displaying the message, "Your Vodacom account is not eligible to enable mobile service on your Apple Watch. Contact Vodacom for more information."

As instructed, I contacted Vodacom in December 2022, but despite numerous follow-ups, my issue remains unresolved. After months of patiently waiting, there has been no progress whatsoever. This level of service is extremely poor and disappointing.
