I'm very disappointed

very bad service, they don't want to refund me, instead they forced me to buy something else or take gift card, since I didn't bring the card that was used for the purchase, my partner who stays in jhn used his card to make the payment, now the jeans aren't fitting well, they took them with the slip and forced me to take gift card, the lady said she's the area manager, phoned speaking rude that it's their policy, I'm never buying again in that shop.
