Forced returns and refunds

[thingz-2-sell]

Why am I forced to accept a return or give a refund to a buyer that orders an item before knowing exactly which item it is they are actually in need of.  (Modems) not being compatible with the service provider they have, then I am stuck with taking a return of an item that was sold as new, and now I cannot resell as new or used in some cases, due to them trying to connect it to their service provider. Now I am out time, money, and an item for sale due to their negligence?

@thingz-2-sell   Sorry that you have a bad buyer.  

This is how the eBay MBG works>>

If the buyer files a refund request saying that the item is not as described then you need to accept the return and issue the return shipping label.  

The eBay Money Back Guarantee overrules your returns policy.   Your return policy only applies if the buyer files a buyer's remorse return:  Doesn't fit, changed mind, etc.  

If you do not accept the return willingly then the buyer can ask eBay to step in and forces a refund. You do not get your seller's fees back, you get a defect and the buyer may be allowed to keep the item.

If the buyer abuses the eBay MBG in some way then you can report them but it doesn't get your money back:

Sellers have protection for return abuse if they offer FREE RETURN shipping on their listings OR if they are a Top Rated seller and offer 30 days or greater returns.  The seller can then reduce the refund amount by up to 50% if the buyer sends a different item or somehow reduces the value of the item.
