No refund for items not in stock. They are running a **** online shop

I bought items on the online shop which stated clearly that is available and in stock. Only to inform me via WhatsApp that all the items I bought online are not in stock so they sent me items to chose from in which I liked only three items but did not like the other two and they were supposed to refund me for the other two items. I bought those items using Payflex . The issue is I have to still pay for the items via Payflex and they are supposed to refund me for those two products they didn’t have in stock. They promised to refund me via Payflex but until now no refund has been done via Payflex and when you reach out to Payflex they instruct you to tell the merchant to refund via their Payflex portal and The Culinarium have not done it. They are ****. Now I have to pay Payflex otherwise i will be blacklisted for not paying while they The Culinarium get to keep my money and no products . DONT BUY FROM THEM!!! That shop is ****ming people advertising that they have items in stock and make you chose items substitutions and items that you don’t get or want you are not refunded . Give me my money back .This is my first time purchasing from them .
