Rediffmail.com — rediffmail and associated facebook account hacked

Date: 3 january, 2020

My rediffmail account [protected]@rediffmail.com has been hacked and the password has been changed. The recovery email and mobile number has also been changed and there is no option for secret questions coming in order to retrieve the password. Also rediffmail is not providing any solution to this problem even though i have cooperated with them and sent all the details asked by them in timely manner.

Due to access to rediffmail, the hacker has changed name, password and personal details of my facebook too. This will lead to the hacker misusing my information and photos.
As a proof, i am attaching screenshot of my hacked facebook account and also list of my friends who are mutual friends with my another close friend (Who has helped me take screenshot of my hacked account).

Pls help me to regain access of my rediffmail account so that i can also recover my facebook account.
