Scratch & Win Fiasco

So on the 26/8/18 my husband wanted to redeem his 5 scratch & win cards that he had. So after buying a few groceries, he hands the cashier his 5 scratch cards. She then had to call the supervisor, Regina, to assist as she did not know how to process the scratch cards. Well, more than a half hour later and now at the Customer Service desk, Regina still could not redeem the scratch cards. Clearly the staff have not been trained!! My husband eventually lost his cool and left, leaving the scratch cards behind. Why promote something and then not train the staff?? Surely a barcoded scratch card that the till operator can scan would have worked?? Instead our time and energy was wasted and we walked away with nothing!! Shocking to say the least!!
