India Govt Mint, Kolkata — Non- receipts of commemorative coin sets ( Proof) of Dr Rajendra Prasad and Rabindra Nath Tagore

Way back in Aug 2010 one set proof coins each of Dr R.Prasad and RN Tagore was booked by me. Ref No for RN Tagore being RRP-907/10-11, FOR Dr R Prasad, not availablre now ( However, D/D no. being 317517 dtd.28/07/2010 on SBI, Jamshedpur). Have not yet received the coins nor any communications from the Mint. May be I was travelling when the sets arrived and not delivered and returned back to Mint. In such case, kindly resend the coin sets ( if additional delivery charges applied- pl specify) to my new address ( since Jan 2015) as " S.N.Sinha, Duplex-97, Vijaya Heritage ( Phase 6th & 7th ), P.O.- Kadma, Jamshedpur-831005 ". Thanks.
