Order received when the payment doesn’t go through

I use Razorpay for the payment gateway for my website?https://www.papeehajewelry.in. Even when a payment is not complete customers see the message “Thank you for your order, please click the button below to pay with Razorpay.” I have tried changing the text with Say What plugin, it doesn’t change the output. How do I change the text to something like “Your payment is pending, please complete the payment by clicking on the Pay Now button below.”
