Flipkart — Doing fraudsters in Refund

Order id OD[protected]
i placed order on 15 oct and cancel my order within 30 minute. Now they are not refunding my amount and told me handle yourself from bank. My state bank of india confirm they didn't receive any money. This is responsibility of flipkart to give refund to customer, not a responsibility of customer to contact bank for refund.
When i call to flipkart they put my call on hold.
I call to them my times.
They are telling seller has initiated refund and giving fake transactions id and told tehy are not responsible for refund.

They are harrsing me and giving mental pressure .
Please redund my 8000 rs.
I have attached where they told go to bank.
My bank didn't receive money from flipkart. So my bank can't help in this case.
