GoAir — flight got cancelled. I am not getting any response from your customer care.

I had booked a flight (G8 293) from pune to bengaluru on 19th march at 1:30 am. I just received an email yesterday that it got canclled. Since then i have been trying to contact the numbers provided in the email as well as numbers of goair pune and bengaluru airport offices to reschedule my flight. I even tried mumbai just to get in touch with someone from goair. The network has been busy throughout or some numbers are invalid. How can you even provide numbers and they dont work at all? What kind of a customer care service is this that has not responded for over 12 hours? I need a response as soon as possible in this matter.
