simply that the deliveryman gave me the package, well not to me, but to me woman .... whatsoever, I do not care, since there had to be signature, and no official proof that I received the package in person

Precisely.

If a fake signature was used, there's no evidence to conclude you personally received the package, regardless If It was handed to your partner.

I could eventually use the DNA method, but I will probably get a yellow flag on my account, right?

What's the age of your account and how many legit transactions, Inclusive of SEs, have been performed?

Otherwise, I can use the empty box, ?

Without even researching the Item, I can confidently say (purely by Its description) that It's way too heavy for the EB/missing Item method.

or else what other technique would work?

The wrong Item received and If the packaging Is compatible, the sealed box method.
