Bajaj Finserv — Cancellation of health Insurance

A few days ago Aditya Birla health insurance of amount 13, 861 with Loan account Number : 405GIPGC322266 was activated on my account without any undertaking or sending information asking me about the activation. I have sent many Emails regarding the cancellation about the loan amount but the Bajaj people just won't do it.
First EMI date is[protected] and if by any chance some amount gets deducted from my account, I will take strict action against this close all the connections with Bajaj and advise so to others.
