Billdesk — transaction not completed but amount deducted.

I have booked jio phone and paid 500 rs from icici bank netbanking vide transaction no. Bil/[protected]/pgmib-/reliancejio_jic. But transaction failed. So, i thought it's a server error. But after some time i get the mail of deduction of 500 rupees from my bank account. But i haven't get any confirmation message or online bill from jio. So please resolve this issue as soon as possible. Help me regarding this issue.
I have booked another phone through paytm which i got confirmation. Please revert that amount.

Thank you
