I booked a flight ticket Booking ID - GOFLI32D[protected] from Bangkok to Hyderabad through Goibibo in 30th March 2020, but my flight got canceled due to COVID.I Tried contacting customer care through call, web form and live chat every possible way. Since from march I tried and finally got a call in October and they said they will refund the amount in 5 workings. But it has been 2months still I didn't receive any refund and I am unable to contact. I tried so many times calling them and submitted many web forms there no response worst experience.
