Both sticks defective, no virgin?

Both sets of sticks were already defective upon delivery. Was built with antistatic gloves. Memory was not overclocked. Memtest showed hundreds of thousands of errors per stick, as if all the memory chips would be defective. Other sticks (Kingston, Corsair) running on the same board, the same memory slots easily.

What also surprised me: Both sticks showed on delivery distinct "rubbing marks" to the contact pins, as if they were already out multiple times and were removed again. I'm going to upload a picture of it. Is this really new merchandise? Or parts from cannibalized computers are relabeled in the name Komputerbay here?

Overall, I am very disappointed. I hope now to get my money back from Komputerbay. An exchange for another set of "new" memory module I want to avoid at the geboteten quality actually.
