Total Garage near West Gate is making a mockery of the Dischem Loyalty Card

Total Garage near West Gate is making a mockery of the Dischem Loyalty Card. I've been filling up my tank for a long period of tiime swiping my Loyalty card whenever I fill up. Great was my surprise when I received an update from Dischem on my merits accumalated over a period of 2 years. The result.... no merits!!
