Go First Airline — GoFirst worst ever experience and worst solutions

GoFirst worst ever experience and worst solutions.
We booked air ticket (on 18th July - about 1 month back) for Kolkata to Bangalore to travel on 16th August. It was non stop / direct flight. But on 1st August, we got a message that due to operational reasons, the flight was cancelled and can be rescheduled to +/- 4 days. Only available options were connecting flights and long duration lay over. We somehow selected Kol-Mum-Bangalore for 14th Aug (2 days before) with 8 hours lay over.

Again today (12th August), 2 days before the expected journey, they have amended the booking. Time different, odd hour midnight landing and sector different. Now it's via Pune. When we talked with the representatives, they said these are the only few options. No daytime or evening landing flight and no direct flights. They suggest taking Kolkata-ahmedabad-mumbai-Bangalore or Kol-Pune-Bangalore. 10-12 hours total time when what is actually needed is just Kol-Blr.

Now in the last moment, how are we supposed to take refund and book fresh tickets with other airlines as long weekend or high demand dates. GoFirst seems to be playing with bookings and taking payment from customers and enjoy 1 month interest free fund collection. And forcing us to travel at their suitable date, time and sectors. Customers are just being made fools by them as we don't have any say in how we want to travel. worst ever experience and worst solutions
