Bajaj Allianz — Policy scam targeted to fresh graduates

In 2011, when I just started working, I created a salary account with Citibank and the guy offered me a Bajaj Allianz insurance policy with 8.5% YOY returns and 4 year maturity period.
Since then, a 1500Rs amount has been deducting from my bank account every month and it's been 10 years.

I am now shopping for a new life insurance policy and I checked with the Bajaj team to close this existing policy but I was told by the Bajaj team that the policy is for a 20 year maturity period with near-zero/negative returns.

This is a complete scam, even an uninformed policy buyer would not have made this kind of policy purchase.
How do I move forward here and close the policy without getting charged the enormous fees on my investment?
