GoAir — Flight cancelled with no alternative

We booked our onward and return flight via go air from Bangalore to Maldives to travel of 14th April and return on the 17tg. The bookings were made in early March and we got a price close match to Indigo. However we chose to book Go Air and not Indigo because of the timings.
Just 2 weeks prior the onward flight was cancelled with no alternative and no confirmation on return flight status either.
We incurred an additional 20k to rebook on Indigo. So far no response from the airline.
