False Advertising - poor service

I saw an advert online and it read online and instore. It is a Fridge Hisense for R3499. I called Game call centre and they confirmed the price sale end date 08-02-2022. I also checked stock at Ballito and they said there are two items. As I'm buying it for my friend she went in store last week Wednesday to buy..she was told that item is non 3499 it's 3999..we showed them screen shots and they were to talk to the manager and to date they have not come back..more surprisingly they gave here a call out voucher but it's for R4299 for the same item... She went on Wednesday so she can get the 10% discount for vaccinated people but that was also not taken into account on the voucher. Why do you false advertise? Today is the end date of the special but still no word regarding correct price. I still have screen shots in my possession which clearly indicate R3499 for the fridge. item code 821291-EA
