MegaU Benefits don't exist

I opened kids accounts for my daughters. I really liked the benefits that were offered by absa on their megau accounts. To my complete disappointment, I reedemed the Debonairs vouchers and went to Debonairs to buy pizzas. The people working there didn't have a clue of what are these vouchers for, eventually they entered them on their system and nothing worked. I enquired at the Southdale branch and the consultants were clueless. One consultants said she hates them as they never work. What is going on here absa, why are you offering us things that don't exists??
