Bad and misleading advertising Pick N Pay and ebucks

After seeing the Burger Fridays add on Friday, 4 March, I was excited about the new ebucks and Pick n Pay relationship. And who doesn't like Burger Fridays. At Pick n Pay, standing at the till to pay, the cashier first complained about "another FNB" customer and asked if my card was linked. I didn't know what she was talking about. Needless to say, Pick n Pay did not pick up the ebucks rewards and short of embarrassment at the till, I paid R100 for Friday Burgers. The add stated I'd only pay R50. As an FNB client and level 5 ebucks, I was sorely disappointed. I tried to Google search how to link my FNB ebucks rewards and Pick N Pay without any results.
