This may happen sometime when the refresh button is pressed after payment or when the backspace key is clicked at the time of payment. However, you will get an order update within 12hours. If you do not get any update, you can just mail to sale@psgvestments.com with your name, shipping address, and proof of payment, so we will pull your order from the shopping cart and will send you an update within 12hours. (NOTE: Please do not clear your shopping cart)
