She used fake signature, writing one letter and some lines around it.
and now wanted to do dna.

That's good news that she didn't use her real signature.

As far as you're concerned, you didn't sign for It, hence did not personally receive the package. The DNA Is well-suited under these conditions.

Thanks for your help once again. I guess I will just check if they would instantly refund me and if they will say something about investigation I will pursue that I will check around my flat once again and will take it as a loss this time. I would rather risk with investigations for more expensive items and have better history.
