State Bank Of India [SBI] — Refund initiated by Ajio but still not received in sbi bank account

Hello sir,
I had ordered jacket and heels from Ajio on 17th December 2021 and made the payment of 2730 through UPI phonepe. But due to some issues i had cancelled jacket on 17 itself which was of rs 1574.55. I got the message of refund initiated on the same day with the refund Reference number PSpPX4sl6pEeylCus3nQ55A. It was expected to be credited within 7-9 days but today its 30th December 2021 but still haven't received refund.

This is urgent, please help me as soon as possible to get back my money.
