India Post
Non delivery of speed post

I have sent a crossed DD for Rs.2 lakhs to my father for registration of a land at nagpur through speed Post with proper address on 11.07.08 at 15:42 from ICF Colony Post Office and till date i.e 16.07.08 (12.00 hrs) my father has not received the Speed Post. What am I to do. I am very stressed and upset as today the money has to be give before registration.
