eSIM not registered on Network for my Samsung Pro 5 Smart watch

I purchased a Samsung Pro 5 Smart watch and needed it to be registered on the MTN network to use it to receive calls or listen to music whilst running etc. without having my Samsung galaxy cellphone on my person. I received a QR code for an eSim to load the plan into the SAMSUNG Wearable app on the phone and it loaded perfectly, however when trying to use the watch independently, the watch keeps on reporting that the SIM is not registered on the MTN network.

I called MTN every day for a week now after logging a REQ case with them - only to be told each time that the case is still under investigation and that no feedback has been received from their technical department. I have also been back to the MTN store at Clearwater Mall where I app**** for the watch eSIM and they are unable to assist me.

Any ideas as to whom I can escalate this issue ? I cannot believe that other owners of Samsung Smart Pro 5 watches are experiencing this issue on the MTN network. I have been an MTN client for more than 30 years and am seriously considering moving to another service provider.
