Indian Railways — TDR not refunded even 7 months passed

PNR No. [protected]: Train Late More Than Three Hours and Passenger Not Travelled. TDR filled on 8th Dec 2016 at IRCTC website. But it is not refunded till now. Lot of communication made in this regard but no proper reply. IRCTC told it is the case of Indian Railway and EASTERN RAILWAY is the concerned zone which will deal with this case. IRCTC forwarded this case to EASTERN RAILWAY. Eastern Railway is not picking my calls and not interested to resolve the issue after lot of emails from my side.
