GoAir — change of flight without information

Address:

Mumbai

My flight was booked originally for april 02, due to lockdown goair changed it to april 19 which was understandable. When i checked my booking online a few dates before the travel date the booking was changed to june 15 without any prior consultation with me, i tried connecting to the customer service several times since i could not speak to anyone i dropped an email asking for a refund as it was pointless to travel in june.in may again when i tried to rebook and change the travel date to may, i realized that the date has been moved to september 13 again without any discussion or approval from me. I called to check the status of my refund request. The customer service number is not available and when you call them there is an automated voice asking to use the website to make changes to the flight when i use the website and enter my pnr it says that the pnr is protected and i need to call customer service. My money is blocked for months.
