Consumer Redressal

My mother Mrs Usha Goel has taken ICICI Prudential Lifetime Gold Insurance policy having following details: policy number: 08939751. Date of Birth:03-02-1960 According to the policy,we have to submit 2000 per month installment for 3 years. We have almost all installment and somehow dont know miss one installment. After two more years policy has to mature. Before six months of maturing the policy they remind us that we have miss one installment so we have to submit 50000 rupees more to continue our policy. It is not possible for us submit that amount so they forfeit our policy with out prior information and send 24848.67 INR rupees demand draft. This is injustice and we feel cheated. They have not informed us about the installment at that time and we want our money back.
