Yes, if you wish to, you can cancel the Auto Debit facility for policies with Annual, Quarterly & Half Yearly frequency. However, auto-debit is mandatory for monthly mode policies. For this, you need to fill & submit the Mandate Deactivation Form available at any HDFC Life branch at least 12 days prior to the due date. You may also place a request for Auto Debit Deactivation by emailing the company at service@hdfclife.com from your registered email ID. If you are an NRI Customer, you need to write to the insurer at nriservice@hdfclife.com.
