Holding offer letter

I have completed almost 5 rounds in Wipro and HR said you are selected in all and HR round will happen soon (few weeks back)

But it never happened! And today when I was checking about the status one of the HR said, that position is on hold and another HR is still asking me to wait and saying everyone went for Pooja holiday so next week only she can able to get the update..

What should I do now ? Any suggestions ?
