Ibibo Group / Goibibo — refund for the cancellation due to covid 19 aas flights cancelled

Address:

Gurugram

I had booked 3 return tickets from chennai to detroit in usa for april 27th 2020 and return from detroit to chennai for 19th may 2020. But due to covid19 and since all international flights were cancelled, i had cancelled my tickets on 5th april 2020. I have received refund for 1 ticket on 8th april 2020 but did not receive refund for 2 other tickets. I tried all ways to contact them but i am not getting a proper answer from goibibo. Currently i see a message in my goibibo account saying there is no refund for my tickets. Kindly help me with the refund process
