ICICI Prudential Life Insurance — fraud policy & company as well

Address: 110059

I am customer of icici prudential insurance, my policy # is 17211387 due to some reason. I was unable to continue my policy. I had paid ₹15000 premium i was unable to pay the premium due to some problem. At that time i talked with customer care regarding forclosure of that policy but he told me that the policy is having locking period of 3 years and i will not get money return, please try to get money after 3 years. Now after more than three years. I talked with customer care, now they are telling that your policy has been lapsed and i will not get any amount.
So tell me is it fair?, that insurance company is not paying back my money.

Please do the needful
