When a merchant issues a refund in response to a Klarna enquiry:
Full refunds (≥95% of the disputed amount) close the enquiry within about 10 minutes.
Partial refunds (<95% of the disputed amount) trigger a 48-hour waiting period before Klarna closes the enquiry.
This delay allows Klarna to detect if additional refunds are issued and helps prevent shoppers from creating new disputes. During these 48 hours, the enquiry is paused and will not be escalated by Klarna.
