I have made three transaction for my product on 26 june and after some time i have canceled one of the, but still i have no updated about my refund amount and not about my order. Status of order is still showing processing. There for i have sent a mail to customer care regarding the issue the said we have still not received you payment may be there is a network issue or something so contact cc avenue, for confirmation i have sent mail to cc avenue they told all the transaction are successful and sent to the merchant, also they share transaction reference number. After that i a calling to there customer care continues but no one is responding.
