Why has no big star congratulated Surabhi on her win, asks the virtual world

When Surabhi Lakshmi won the National Award for Best Actress, there was a deafening silence from the big league actors in Malayalam, none of whom congratulated her. This was noticed by netizens, who commented that it's a shame that the superstars of Malayalam wouldn't congratulate someone unless they are a superstar. When it came to the assault on a top actress, all the actors had reacted, why the silence now, they ask.Manju Warrier was probably the only big actor who congratulated Surabhi on her win.
Surabhi won the top honour over Aishwarya Rai, who was the other contender.
