Aviva Life Insurance Company India — Life insurance

I am Dr. A.K.Basu, Associate Professor in Raghunathpur College, Purulia, WB, PIN-723133. I purchased one policy in the name of my wife Mrs. Sumita Basu paying Rs. 3000(three thousand only) as initial premium (Policy No.EPG1165036, Dt, 30.9.2005). Next premium I paid Rs.6000(six thousand) but the receipt bears a new policy no.-NNU11137124. When I paid another premium of Rs. 3000(three thousand) another new policy was issued (Policy No.-REG1564286). All such policies are issued by Asansol Kumarpur office. I visited there times without number but they did not pay any heed to my several requests to settle the matter so that I could continue my policy premiums.
I thought that my hard toiled money is cheated.
But to my utter surprise I started to receive several calls from 27.4.2017 onward that I could get my money back if I visit your office in Sector 5 in Salt Lake, Kolkata. In response to repeated calls I visited that office on 11.5.2017. They told me to deposit further Rs.20, 000(twenty thousand) immediately and I will get Rs.45, 000 (forty five thousand) in 120 days. I did not agree as I thought I could be deceived again.
This is the brief note how I have been deprived of my honestly earned money.
I request you to take immediate measure so that I could get the principal at least I have deposited.
I await your response
Dr. Abhash Kumar Basu
