No help with supposed partner store rewards

I have been trying to get assistance over the phone and via e-mail to understand my Vitality rewards on Discovery bank. I made a purchase at 2 partner stores and cannot seem to get anyone from Discovery bank to assist with where I see exactly what my "reward" discount is from shopping at a partner store. It used to be so simple to see with the old Discovery system before the separation into Discovery bank - now it is actually disappointing and frustrating trying to get any help!
