Picknpay Somerset Mall

I am utterly disgusted by the customer service I received at PicknPay Somerset Mall. I had a trolley full of grocery and I asked the cashier for the Picknpay card so that I can get the discount. She was very rude and uproffesional. She told me that the cards are finished and I asked her what can I do then to the discounted prices. She was very rude and told me I can leave without buying if I want to, it is none of her business what I do. I am so dissapointed by that customer service. I left and went to Checkers and recieved the best customer service. The fruit and veg manager at Picknpay did not do anything to resolve my problem. I will never ever buy at Picknpay ever again. They should teach their staff some respect.
