[Seeeeee]

I will just tell em I didnt sight anything and I didn't get anything that's it. Hope they wont push it its only 100e.

Did you actually sign the package?
If yes with a fake sign?
If no you are good to go

No I didnt but what would happen if I did

a fake sig wouldn't change much, just means you'd have to tell the rep you never signed anything and to provide proof the signature is yours, because you know for a fact you never signed anything. In theory, you're putting them at fault for not verifying the person signing was the correct recipient.
