Subscription cancelled ahead of time, but Apple auto debited the renewal fee

I had opted to cancel my 'LinkedIn Subscription Premium Business' and the expiration date shown was August 14, 2023, 1:56PM IST.

In the Subscriptions section of my apple ID, I can see the expiration date as August 14, 2023.

That said, today (on August 13, 2023 at 7:53PM IST), apple auto-debited an amount of 3299 Rs from my account; for a cancelled subscription (with expiry date of August 14, 2023. I cannot see this purchase info under my appleID; but I can see the debited transaction in the bank statement

Since the purchase is not showing in apple, I am not able to use the 'Request a refund' option.

Hence, I need assistance in getting this amount (3299 Rs) credited back to my account.
