Rediff.com India — my rediffmail account seems to have been hacked

Address:

Kamrup Metropolitan, Assam, 781014

My rediffmail account...[protected]@rediffmail.com seems to have been hacked. I am not able to open it. When i put it in i get the message that the username does not exist. I have tried it several times and have also attempted the forgot password and forgot username options. None of this is working. I would be grateful if you resolve this issue quickly as many important official mails come to this account.
