Ibibo Group / Goibibo — Flight cancelled by airline

This is my Booking Id - SEA[protected].
I had received a confirmation on refund as credit note..but have not yet received the credit note.
I tried n number of times to connect the Goibibo team for my update, it’s been more then 2 to 3 months but in vain..would request you to please go through my issue and resolve it.. I am also attaching few email conversations for your reference for your better understanding.
