Rich Infra Not issuing maturity amount

As My wife invested Rs. 100000/- in rich link/RLS036 plan for 3 yrs. at one time mode on dt. 19.3.13. Its maturity on dt. 19.3.16. My Application No. is 1081497. Registration No. is RLS036/25248. I submitted required document for maturity amount at 21.3.16. The chandrapur branch office head mr. mangesh said it will took 2 months for maturity amount. I agree and wait for 2 months. From 29.5.16 to till now I ask for my maturity amount to mr. mangesh. But every time he gives some reason and delaying the amount. Till date we have not received our Maturity amount.
