Claiming DNA on pick-up points is destined to fail, since you had to show your ID to receive the package and that is enough to confirm your identity.
I assume that EB is out of the way since PC's usally weight over 120 grams
Wrong method received might work
Boxing is also an option

Your account is in very good shape so just try your best to avoid major mistakes within SE and you should be refunded

Well they have no proof of me showing id, which means its my word against theirs cuz no pictures were taken

Are there no security cameras there? That seems unlikely.

I don't think amazon or the shop would go as far as to look at cctv footage that seems so unlikely.
