GoAir — Unable to contact GoAir for Flight refund C4N9TI Depart

This is the third time my flight was cancelled by GoAir. I'm unable to place a call on either of the numbers provided by them i.e.[protected] / +[protected]. I'm also unable to make cancel the flight via manage booking option it gives me the error: Agent is not authorized to ignore restrictions.
I need my refund before the date else I will not get my refund from Travel Agent.
