Dischem - Victory Park - Poor service from Manager

Out shopping and i noticed an advert for 30% for Fusion Shaving blades, called the person working to validate if i would qualify for the Fusion Power Blades and he confirmed YES i would. I grab 4 packs as it was a good deal. When to pay and then told i did not qualify. Ask to speak to the Manager and he said he would check and says to the display Advert was old and not valid. I said i confirm with your staff and the T & C states till the 14/12/2022. Fortunately i have the photo of the advert. So i explained to him TCF and false adverts and wasting my time and says to me he can only discount 2 packs and not the original 4 which was scanned. He starts to calculate the discount and could not the calcs correct, so i had to take out my phone and show him the correct amounts. Extremely poor Client service, staff not sure whats happening and Manager was rude and could not calculate simply %.
