Poor customer service

So, i made a laybye 2 months back then i took it out yesterday. and when i get home only to find that my daughter's clothes is not fitting her then i came back today for exchange. the cashier and store manager told me that the is no refunds for laybye while the receipt says another store. while we were arguing about the receipt the manager decided that its fine he can give me the refund but only with a gift card. i then said my problem is the same clothes that i bought they no longer in store that is why i want a refund but if it wasn't that i was gonna exchange same thing.

I requested for my money then he said i must wait for a customer to come to the store to buy the same clothes for him to give me a refund which it doesn't make sense to me. he said i can wait until the shop closes. i arrived at the shop at 16:00 so meaning i will have to wait for 2 hours. not sure what's gonna happen if no one buys my items.
