Poor service

I have a S23 ultra, with sim cards in the device. I got a samsung watch 6 with thr lte function. They activated the one number and eSim for my watch. Now my phone keeps giving error message sim 2 not allowed. I have been at 4 Vodacom stores and multiple calls to the call centre and no one knows whats worng. The phone has been booked into samsung, no issues with the device. If i use a diffirent provider sim card in my phone, it works 100%. I am now stuck with a cellphone i cant use and a smart watch. All.purchased from Vodacom. I can not use and Vodacom's incompetence to fix this issue for the past 6 weeks. I am still waiting for them to get back to me. The stores just tell you go to another store or phone the call centre. Nobody can help, it seems no one at Vodacom knows what to do.
