Punjab National Bank [PNB] — premium term & maturity term duration same - two policies

Hello: i took 2 policies - premium 30k and 50k annual. The agent mentioned 5 years premium and 10 year maturation and the returns will be doubled (Near) after the maturation.

After 3 years of investing i realized that my policies are for 10 years and maturation is for 10 years and the returns are less than my total investment.
30x10 = 3 lakhs. The sum assured after 10 years is 2.92lakhs with some dividends which are not promised.

I wrote to grievance cell. Ms nidhi tuli, senior executive. Instead of helping or resolving she is indifferent.
By policies there is nothing that can be done.
Can you please suggest what are next steps to me.
