Indian Railways — Refund of tdr filed

I have filed a tdr on 16th april 17 (Transaction id [protected]) (Cancellation id: [protected]) (Registration no:[protected] reason being tickets were partially confirmed and waitlisted for the passengers. But i have not received any communication from railways since then. It is showing as cr registered only, even i have mailed (Ticket id irctc #5701761 & [irctc #5738621) twice for the current status. Kindly help me in getting the amount refunded as soon as possible, as its been a month since i am chasing the concerned authority.
