Ebay return with a twist

[jebedar123]

I sold a laptop. The buyer complained about the battery and took it for service to check they said it needed to change the battery and the whole top chassis of the laptop (all free of charge because it is still under warranty). 

The buyer returned the laptop and so I took it to repairs to get it checked. To my surprise, the technician told me it had already been serviced with a new battery and a keyboard while it was in the buyer's custody.

So my question is, since the item has been tampered with and modified, can I refuse the return? Consequently, this isn't the exact item I sold; it has new/different parts from what I sold. So, can I refuse the return based on it alone, right? They shouldn't have sent the laptop for service before sending it back, right?

I appreciate any help you can provide.
