[Resolved]  Redbus — refund not received yet

I have booked a ticket from nagercoil to coimbatore on 29th and i cancelled it immediately
But more than 30 days have been completed and yet i haven't received my refund amount to my account.
I called redbus for more than four times and they aleays providing a reference number and asking me to go to the bank.
And rejecting the calls before ending my query.
I request you to help to get my refund amount from redbus.
Thank you
