I, mrs archana agarwal, a senior citizen, housewife, bought the certificate of property from alchemist infra realty on 26th march 2013. It matured on 5.3.2016 but not yet received the amount. When i bought the certificate, i was 61 years old and thought that in 3 years of time the money will double and i will get the money back but i am 70 years old and need the money because my health is worsening day by day. The allotment number on the certificate is rx00039198/99. Please help me as i need the money for medicines and day to day living. The agent who help me to buy the certificate died in a train accident one year after the purchase of the policy. So i do not know how to get my money back. I do not know how you will contact me with the answer. It is my hard earned money. I am very poor, always tried to save bit by bit and then bought the certificates so that when i need it then i can use it in harsh times but did not know that i will never get it back. I am very depressed. Please help.
