Ibibo Group / Goibibo — flight ticket booked from goibibo

Address:

201002

I booked flight ticket from goibibo for 10th april 2019 from new delhi to ahmedabad, the airlines denied to onboard us due to over boarding, i cancelled my flight and asked goibibo to process my refund. It's been more than 90 days goibibo has not provided me my refund. I have even submitted all necessary documents regarding the same. The goibibo app says that they have refunded my money as well as there system says that they have refunded my money but the bank denied that no transaction took place from there provided transaction id. I have submitted my bank statement also still they are not providing me my refund and just say we will call you within 24 to 48 hours but no one calls.
You can see how these people do fraud my there own conflicting chats.
