You can accept or refuse a partial refund in the Resolution Centre. A partial refund may be offered when you receive an item or service significantly different than what was described. 

1. Go to Resolution Centre.
2. Open cases from the list.
3. Click Respond next to your case.
4. Accept the seller's refund offer or suggest a different amount.
5. Click Submit.

As soon as a seller initiates a partial refund, you have 10 days to accept or refuse the offer. If the refund is not accepted or refused within that time period, the offer will expire.
