Horrible service from Bluff manager

Bluff store manager is refusing to refund my purchase. I have provided her with a receipt but apparently the card on the slip does not match my card so she said it’s a credit card and she cannot refund me I must present the CREDIT card that I do not have???? I opened my apple wallet/ pay to show her the transaction and I also opened my banking app to show her the transaction and the amount that went out - with your store name as reference. I requested the refund the day before yesterday because the person that I bought the item for said it will not fit properly she uses a king bed and I bought her a queen set. When I went to the store the cashier said he cannot refund me because of the card number miss match, he called the manager who also asked for my virtual card number and physical card number and refused to refund me insisting that I have another credit card which I am not showing them?? I left the items and asked them to escalate further as I don’t have another card so it could have been their system error or something else. I waited till date no one got back to me. I went back to the store and asked if there is any feedback on the refund and the manager said no she is still telling me what I refused to hear the other day ( with an attitude ) she ignored me and had a conversation with one of the employees while I was in front of her waiting to be assisted on both occasions. I am not happy with the service and attitude she gave me and I am still waiting for my refund. I left the items and receipt at your store. Can you please resolve this soonest.
