GoAir — Postpone and prepone of flight without intimation

We had a booking of flight for 4 passenger from Mumbai to Jaipur on 23 March 20 via flight no G8 2607 of Goair against PNR E5YF2P and return flight from Jaipur to Mumbai on 28 March 20 via flight no G8 2608 of Goair against PNR YFE5XH which was cancelled due to covid pandemic. After which our purpose of visit was meaning less as we did not wanted to fly we tried to cancel tickets which was restricted by Goair, we were not even allowed to change destination or passengers in said ticket and was only left with one option to fly to Jaipur.
Now after 7 months we booked ticket to Jaipur as per restriction of destination change by Goair for Mumbai to Jaipur On 30 Oct 20 via flight no G8 2607 for 4 passengers by paying extra INR 4700/- against PNR E5YF2P. And return flight against PNR YFE5XH by paying extra INR 4908/- Now the flight timings for G8 2607 was 16:00 departure and arrival by 18:10 at Jaipur. On 28 Oct 20 we received a message stating that flight G8 2607 on 30 Oct 20 is preponed to new timing 14:50 departure from Mumbai.
Now when we reach airport on 30 Oct 20 we come to know that the flight G8 2607 has been postponed to 31 Oct 20. Now the airport staff of Goair was not ready to listen to our problem after struggling for 1:30 hrs we were asked to fill refund form on airport and left stuck with no option other than to try for other airlines.
Now after searching we find out that we can book Indigo flight to Jaipur for which we need to pay INR 19338/- for flight no 6E6998 to Jaipur against PNR VWM9RN for 4 passengers.
The service and response provided by Goair is pathetic and completely irresponsible. Due to there irregular changes we have lost on lot of money and additional stress was created.
Also would like to complaint that Goair does not provide a single free sitting while doing web checkin not even the middle seats. Then what for do they take money from passengers to make them travel when they are not offering any seat on flight.
This does not end here on our return flight no G8 2608 from Jaipur to Mumbai against PNR YFE5XH which was timed to depart at 18:40 hrs.
Now due to previous experience we tried checking for flight flying schedule on 31 Oct 20 where we come to know that flight G8 2608 has been preponed to a new time of 08:10 hrs without any intimation or information received from there end. How can Goair plan anything on our behalf how can it cancel or prepone a flight by 10 hrs this is so lethargic and unprofessional.
It was due to our active way that we found out that the flight has been preponed by 10 hrs otherwise we would have missed our flight.
Also we had few meetings planned which cannot be completed due to timing change done by Goair.
We would like to get apologies from Goair and reimbursement for losses we have attracted due to there irresponsible and un professional behaviour.
