Firstcry.com — order canceled without informing and no refund

Order id 7262921su44348306 which was done on 31 oct 2019. Order shows canceled without informing customer and no refund was provided and in queue. I was waiting for delivery and when logged in got surprised that you guys have cancelled order without any updates and adjusted that amount with any past refund. I called customer care where they are telling of some past pending return while there is no such case. Every one knows that ecommerce company will not initiate refund without return.
