Thank you, but another thing comes in my mind : is it an issue if the item I want to get a refund from, is almost out of stock ? In the most extreme case, I buy the last one in stock, I receive it and then I claim it's another item, if they check their inventories they'll see they don't have it anymore and they'll "know" I'm the one I have it and then my SE will be f*cked up ? What do you think ?

It's always good practice to purchase a wrong Item that's not low In stock.

As such, they'll have ex-amount In their Inventory and more often than not, they won't bother doing a stock count.
