I have booked the flight on 17/09/2021 evening and due to happyeasygo app side issued flight booked in reverse like booking for bangalore to agra and due to Happyeasygo app it booked agra to bangalore. After then i checked the ticket and directly call to indigo airline and they also said issue is happy easy go app side. then as per DGCA rules airline refunded the full amount without any deduction to Happy easy go company but Happy easy go team said they will not refund the full amount i.e. Rs. 3884 and only refunded Rs. 3484 deducted the convenience fee. I have write many mails regarding this to cs@happyeasygo.com but no sensefull response from them instead copy paste automatically mails. 2 reasons are listed that why they should refund my full amount i.e. Rs. 3884. -> as per DGCA rules airline should refund full amount if booked wrong ticket and informed in 24 hours. airline refunded full amount refunded to Happyeasygo so they should also do the same. --> The issue is happy easy go app side that they booked my ticket in reverse direction. so due to happyeasygo app facing issue and this is not my fault. Kindly request you to please help me on this and get my full amount refund back.
