eBay return request

Hi,

 

I recently sold an AM4 Motherboard on eBay. I tested it was working numerous times before shipping it out and ensured it was packaged properly. The buyer previously bought another motherboard off me several weeks ago and had no issues.

 

They received the motherboard yesterday at around 10am. Today I've logged in to see that a return request has been made for the recent board I sold. 

 

I'm trying to find the reason for the request but can't find one. When I try view it, I get the following message: 

 

"We took care of this return for you

You don't need to refund the buyer, and you will not receive the item back. Thanks for trusting Simple Delivery."

I looked in my inbox and see the following updates:

 

1st message: 

 

 

"We appreciate you trying to work things out with the buyer. They've asked us to step in and help resolve their return request, so we're going to take a look at the details of their case and decide what the next steps should be.

You can expect an update from us within 48 hours. There's nothing you need to do right now but, if you have questions, you can contact us. Thanks for your understanding."

 

2nd message: 

 

"We're contacting you about a return request your buyer opened for ASUS PRIME B550M-A WIFI AM4 AMD Motherboard. This order was processed through Simple Delivery, so we handled the return on your behalf.

 

You don't need to take any action and you won't be charged for this refund. We're contacting you about a return request your buyer opened for ASUS PRIME B550M-A WIFI AM4 AMD Motherboard.

Both these messages in my inbox were sent at the same time today (basically 30mins ago), so it was handled almost instantly. I can't find out why a return request was made.

 

I'm a new seller, so not sure what this means. Not sure why I wasn't given enough time to respond and why I can't seem to find the reason for the request.
