Bajaj Finance — activation of insurance against purchase of mobile

This is to inform you that recently i purchase mobile of rs.13000 from my bajaj finserv emi card.1st month emi was deducted correctly.. And suddenly 2nd month they have deducted extra 380. When i enquired in bajaj officethey told insurance of rs.2000 was activated against mobile.. For which i never gave confirmation.. Neither iam aware of it.. It was activated without my knowledge and never i have received any info abt this insurance. Now i told them to cancel it and went 5 times to bajaj office they r telling freelook period is over and cannot be cancelled and harrasing me unecessarily to pay for insurance of rs.2000 for rs.13000 mobile. I will not pay any insured amount because i m not interested to take this insurance. Kindly request you to cancel my insurance as soon as possible and send me the confirmation of cancellation of insurance immediately. Neither i have given any telephonic confirmation and neither while booking the mobile for activation of any insurance.. This was all done without my knowledge.
