compulsory insurance

i purchased tv and fridge in showroom by EMI . so i signed all the agreements , the payment will be payed through bank to the bajaj finanace company . after one week i received a message that i have been entered bajaj life insurance . so calculated the amount of EMI , i find that extra charge has been implied on EMI . i took all the documents and went to bajaj finserve, they said it cannot been cancelled what i want to do . i haven't signed any of insurance document and there is no particular column of life insurance detail ,before signing the agreement i read all the detail so i felt this is sort of fraud i asked to cancel that but they are not responding . so what i want to do . it is not a product insurance its life insurance .
