IDBI Bank — amount is not credited

I was customer of idbi bank, surendranagar bearing salary account no-[protected].
My account is closed on 9 april 2018.
I have refund issue from flipkart. They told me that your amount is credited to your account. They share me transcation detail as below.

We would like to inform you that your refund from flipkart of ₹ 719 is successfully initiated with the transaction id: p1804231359274181001425 and the arn no is: 74332748116811571330363 on 23/04/2018.

If the amount is not credited, we request you to contact bank with the arn/rrn. I have contacted my near by idbi bank with arn but they told me that due to account is close they can not do any thing with arn and they told me that amount is goes reverse to credit source.in this regarding i have contacted with flipkart they told me that seller did not get amount reverse. So. You have to raise chargeback issue with bank. How i get refund please help me to getting refund.
