Rediff.com India — 4 different rediffmail account not opening , suspect hacking

Hello
I am Unable to open all of my 4 rediffmail accounts with the following user names
all my passwords and usernames are correct but for all the accounts, it's showing wrong username and passwords. Please tell ASAP that it's a technical glitch of rediff.com or our accounts have been hacked. Your phone number [protected] is continuously going engaged on calling so there is no telephonic customer support available from rediff.com when it is needed most. Your delayed response in providing a resolution will significantly harm the customers account privacy and security.
Please resolve this issue immediately.
Thanks and Regards
