What does exactly open box delivery means? Got scammed

I ordered a pendrive, & it has open box delivery. As you know delivery boys are always in hurry & so they open the box & get the otp n left. After few min i put the pendrive in laptop to get some data but the pendrive didn't work & i tried in different ports & laptops also. After that I call to customer they said it's an open box delivery we can't do anything? Is there anything I can do & what does open box delivery exactly means? Like if you buy any electronic item you'll check after sometime. A customer will always thought open box delivery means the actual product is there or not but in electronic items how will you know the item is working or not.
