Vistara Airlines — airlines were not supportive

I have taken ticken from Wenzhou to Madras (connection Flight). As the airline from Wenzhou to Kunming had delayed, I had missed the flight from Kunming to Culcutta. From Kunming, the airline had arranged a ticket for the next day for free of cost. Once I reached Culcutta, I had reported the issue at the airline counter (Vistara Airlines). But they were not ready to provide the ticket for free. The airline staff from Kunming informed me that Vistara will also give the ticket to travel as the flight missed was not my fault. But they did provide any ticket. Later I had forced to take another ticket of Rs.11104
