HDFC Bank — credit card complaints not resolved

I have been misguided into hdfc ergo personal accidental policy by hdfc officials claiming to be my cards relationship manager.
It was earlier informed that the policy is free and the amount will be deducted from loyalty points.
Moreover despite complaints and mails the bank has not resolved my complaint yet. Inspite of resolving the complaint they again misled me towards cancelling my cancellation request by some call from the bank official.
Get my complaint resolved at the earliest or i will escalate the matter further.
