Axis Bank — payment debited

On 28th feb 2018, i ordered some stuff from one site and payment was to be done but the message never pop up, though the payment was debited from my account but not reached the specific site. Then i decided to cancel the order but payment was deducted after that cancellation and not refunded yet. The payment was being done through paytm. I had a word with the site executives but payment was not successful on their end and never reached them. Please look into this matter and resolve the issue.
