Zivame — Refund not reflected in the bank account due to closure.

Refund of 606 z coins was done, but wanted it transfered in bank account. Due to closure of account didn't receive money back. They say refund has been completed, which is not possible as account doesn't exist. I even submitted all the details -bank closure statement, declaration form from bank, still no solution. All they say is wait 72 working hours, no one responds to emails or calls back. Very poor customer service
