Vodacom One Number - Horrible experience for an Apple user

I have been trying to activate one number to connect my Iphone 15 promax to an Apple watch ultra 2(one number) since the 26th of June. Every time I try to activate the mobile service from the apple app I get an error "Dear ....., your Modify Order ONLINE-*** for your Vodacom number *** has been cancelled."

I have visited the stores almost 10 times now and get told different stories all the time, even being advised to do a sim swap to a physical sim then next I am told to get back to an esim. Now for the second time someone from Vodacom says an esim doesn't work and I have to do a SIM swap to a physical SIM, the opposite of what I did the previous day.

I wonder if these people are trained and if so why would they all say something different all the time?

Interestingly the error message is the same regardless of whether I have a physical or esim.
