Indian Railways — waiting list ticket refund

Address:

Raipur, Chhattisgarh

I was booked a ticket on dated 16.08.18 for a journey on 21.10.18 from bhatapara to howrah in train no 12809 along with my 15 months baby.
But the ticket was not confirmed and as the counter became close hence i am not getting any refund against my pnr no.[protected].
Hence on behalf of this condition i humbly request you to kindly do necessary steps to resolve this issue.
