Plethico Pharmaceuticals — non payment of fixed deposit after maturity

Address:

600092

I have fixed deposit of 1.20l in my wife's name g. Mangalam which got matured on 14th april 2014. Till date i have not received interest and principal. There is no response from them even after 4 years of maturity. Since we are not residing in the city where the company is functioning, we are not able to go and meet them in person.
We are from middle class family having lot of financial commitments like daughter's marriage etc.
Kindly consider this message as official complaint and do the needful on top priority basis. I also humbly request the company's management to repay my fixed deposit in responsible way.
