their website sends our customers to credit card payment gateway hosted website after they finish one page checkout, very frequently some of the customers get sent back to their shopping cart instead of being redirected to the payment page. it might be a cookie or session issue. this problem is getting quite serious recently and they wonder if anyone can help fixing this.
