Rediff — ste not working

Address:

Bangalore, Karnataka

It has been almost one weeks and I am unable to open my Rediffmail account. It always returns an message that 'Our servers are temporarily facing problems, try after sometime'. Since three weeks I am facing this problem. As well there is no contact / phone or email where we can raise this issue with rediff. I did try using there feedback system, but no response for that as well.
I expect a quick resolution from rediff and get the email access resolved ASAP.
