Pnp woodmead lets us down

Please do not create an incentive tou cannot provide. Pick n pay woodmead launched a special for card holders on house of coffee beans only to let us down. We send am sms to tge right number but we didn't get the discount at the till, we refused to take the cofee beans bag at. The original price as the difference is around 60 rand!!! The superviser didn't think to come up with a solition.
