Rediff.com India — Lost access to my rediffmail account and unable to login

Address:

1st Floor, Mahalaxmi Engineering Estate, L. J. 1st Cross Road, Mahim (W), Mumbai, Maharashtra, India - 400016

My name is Harish Sikka and I lost access to my official Rediffmail account today (i.e. 24/05/2022) and am unable to login now. Despite being pretty sure about my password it shows it to be incorrect and the recovery email and phone number it shows are nowhere even familiar to any of my knowledge. (The email id in question is - [protected]@rediffmail.com)
It is my official working email id and hence the issue it quite severe. Please help resolve my problem as soon as possible.
