Caratlane — refund not reflecting in my bank account yet

I had made purchases via my debit card on Caratlane. I had cancelled those
orders after a few days. They stated that they have sent the refund via their payment gateway PayU.

I then received emails from email id [protected]@payu.im stating refund is being processed for all the cancelled orders on Jan 29 and 30 via
PayU reference ids [protected],
[protected], [protected], [protected], [protected].

Caratlane provided transaction references numbers for the same as [protected], [protected], [protected], [protected], [protected].

However it has been more than two weeks of business days and I still have not
received the refund in my bank account.
