Mobikwik — Refund of my cancelled transaction

I have paid for indane oil gas booking in mobikwik at 24th July, 2020 of the amount of 628.50 rupees. But on the day itself, we had cancelled this order at indane gas office. And they also initiated the refund at 24th July itself.. but even now..my account has not credited the refund amount. I have complained already three, four times. But no one is responding for my issues. It's very problematic suituation for me..over mobikwik.
