Zee Tv — zee5 app refund not processed

I subscribed to zee premium and used it on my android tv. Aug update of zee5 removed support for my tv. I contacted customer care. It went on for a month of email exchanges on ticket number 518898. Then on sep 13th i received attached email from zee5 that my refund will be processed within 7 days. I have still not received the refund. I have sent umpteen emails and zee5 app to reach out to customer care but to no avail.
