Very disappointed shame

Makro Ottery, why am I forced to get a loyalty card in order for me to b able to purchase from your store. Was at the store on the 17/01/2024 and I was not allowed to purchase anything as it's a store policy that a customer must open a Makro card in order to be able to buy. You can't for people to take you card if they don't want it. I left the store without the items I intended to buy. I'm so disappointed in the way you are treating customers
