It's worth attempting to box said company with random items and make it clear on the packaging that the item had been 'tampered' with, although the chances of this working are pretty slim.

You're not supposed to know that the package has been tampered with during transit, so marking It as such, Is an admission of guilt.

a lot of these technology companies don't check their returns and or send the replacement as soon as they receive the item in their warehouse.

Marking the package as tampered (hence a damage report will be raised by the carrier), will give the company reason to check the return. As such, the SE will fail.
