Axis Bank Promotional Emails

Hi Everyone! I need help regarding re-subscription of Promotional communications from Axis Bank. I have mistakenly clicked on the unsubscribe link given in the Axis Bank promotional email and now Marketing emails which includes various time based offers have stopped receiving in my email ID. Axis bank support is of no help as they are not understanding the issue and keep blabbering same line that your email id has already been registered with us. Please anyone knows how to subscribe to Promotional/Marketing emails again from Axis Bank?
