Due to Sudden Lockdown announced by Government of India due Covid Pandemic we could not travel on above air ticket as all activities put on hold.
We didn't received any refund against above booking inspite of passing long time.
We approached Indigo Airlines and they intimated us that refund against this ticket was already processed in favor to Happyeasygo in **/**/**** and advised to contact them.
We are repeatedly following up with Happyeasygo through email but they are not cooperating. They responded once that they will refund after we put refund request on their website but there is no such option available on website. This was also intimated over mail but they are not helping for this. None of their contact numbers are reachable.
