My Go Air flight G8-136/171 which is scheduled for 17th september 2016 from Patna to Pune has been cancelled.I got mail from Go Air regarding this and they have provided phone numbers to call them for any query. But on calling them no one is receiving the call from past 2 days. Please inform me as soon as possible whether Go Air will provide me with another flight or will refund the money back. And when can I be assured of this as I have to plan my trip accordingly.

Please help me with it as soon as possible.
