Same flight has been canceled for 3rd December and rescheduled for 4th December. I have not received any message and email for same. On 2nd Dec 2020 I Web Checked in by selecting seat as its mandatory at present for Covid 19 and I am surprised when I took print out i came to know that web check in is for 4th Dec 2020. I checked my booked ticket and that is for 3rd December 2020. I tried to contact Go Air and Make My Trip unable to get call after lot of harresment i am able to contact make my trip and i registered my protest by ref no 16069127 and cancelled the flight booking and Make My Trip told me as flight is not operational i will get full refund. But to my surprise Go Air and Make My Trip has deducted cancelation charges INR 4856.00.
