Rediff.com India — Email ID hacked and security number and recovery ID changed

Hi,

My husband's rediff account has been hacked a few months ago. We've been trying to get it back but that dint happen coz all his information, recovery ID, phone number and security questions have been changed.

His Email ID was [protected]@rediffmail.com

The alternate ID that was provided has been changed too so we did not get any notifications about the changes made. So Can the ID be recovered?
Can the alternate ID be changed to [protected]@gmail.com

Please help me recover the account as soon as possible as it is very important as his FB account has been changed twice already.

I request you address this as soon as possible as what all information the hacker can use is uncertain.

Hope you guys provide help on top most priority.
