H&m — Refund taking too long

I placed an order on 7april2022, on h&m.
Order number: [protected]
also made the payment (898 INR) through debit card but for some reason you couldn't generate the receipt and my order got cancelled at the very moment automatically. But money has been deducted from my account and i still haven't got the refund yet. It's been 19 days at this point. Please refund me. Please help.
Hoping to hear from you soon.
