You can only get refunded if you have a credit card at pick n pay clothing Polofields crossing

I went to PICK n PAY CLOTHING at POLOFIELDS CROSSING for a refund and didn’t like how they treated me. I came to the store to buy my items cash and now that I needed a refund they then tell me that I couldn’t get the refund in cash because there’s no money in store and that they could only put the money into a credit card. Who’s problem is it that they do not have cash? When I come with MY cash to the store, they took it, but when I need the money back because I do not want the item anymore then I should get stressed. What if I needed the money urgently to go pick something at a different store? Does that mean that I need to wait 7 days to get the money back? The manager came out and heard my query and still kept quiet and allowed the cashier to treat me like that. I’m honestly not satisfied with this pick n pay clothing. I regret ever buying there now.
