Yesterday i try to purchase enfold theme and add to cart but because of insufficient balance the payment couldn’t processed and then at that time i close my browser. Today i recharge my card and again add to cart and process the payment but because of yesterday cart, i payed double for the same theme so i need to back my extra payment.
The best way to get this solution is Contact your purchased Theme Author and told the fact and request them to give refund for one Item where you purchased twice. I am very much expecting the theme Author will assist you to fix it and will provide you a link how to request refund
