Asking for refund : theme removed just 4 days after purchase!

Dear Team,
We bought a theme on 29/05, then 4 days later it was removed! We even contacted the theme author via themeforest about a pre-sale question and there was no mention that they will remove it!
Now we are in a dead road! The site is not live yet and here is the theme with dead future!
Can we ask for a refund?
Yours,
