How do you cancel a transaction without getting a defect?

Good afternoon~

 

 

If an order was refunded, the next step is to cancel transaction, right?

 

Now, I wonder which reason will land a defect on my account and which will not?

 

 

"ran out of stock" / "sold to someone else"  these 2 are no-brainers

 

"other reason" also counts as a defect, which I found out the hard way...

 

 

"Buyer changed mind" will NOT cause a defect, I guess.

 

 

Then what about the rests....?

 

Please share some experience.

 

Thanks.
