Zara — Refund not recieved

I made a purchase on zara for the amount 5980 on 23 march 2033 and made tha payment through upi.. I made the cancellation within half n hour on the same day itself and not even the product was dispatched or received yet my amount is not credited back to me . It’s more than a month and their team only says that financial team is looking into it yet no response from their side..
