Samsung voucher issue

I'm quite frustrated as I've recently acquired an S24 Ultra from Vodacom and am facing recurring glitches when I attempt to claim my voucher via the Samsung Members application. Despite ensuring that my email details are accurate, the app stubbornly persists in declaring them invalid.

This message serves as a direct request for your aid in redeeming my R1000 voucher. Prior interactions with your consultants have led me nowhere; they simply tell me to contact Vodacom, which baffles me since the offer originates from Samsung's own promotional platform. When i questioned it the situation was only made worse when the consultant terminated our call without a satisfactory explanation.

I urge you to expedite a solution and guide me through the necessary steps to successfully obtain my voucher. Your prompt resolution to this aggravating situation would be greatly appreciated.
