Frustrating and Unreliable Experience with Vitality Mall Vouchers which don't work in stores

I am leaving this review for the benefit of any potential customers, as Discovery itself does not seem concerned about addressing these issues.

The Vitality Mall concept does not work as advertised. If you are considering the Vitality product, be aware that the cashback and voucher rewards often fail. Every time I try to use my vouchers, I receive an error in store stating that they have been “burned”.

When this happens, I am forced to call the call centre, only for the issue to be referred to another department that only communicates via email and cannot be contacted directly. The turnaround time is supposedly seven (7) working days, yet my issue has remained unresolved for over two (2) weeks. Even then, there is no guarantee that the vouchers will work once the issue is “resolved.” It feels like a gamble each time.
