It means you have done 2 things wrong

Firstly, have you used Amazon reciept? I believe it's not because of the quote "Please contact your retailer" but they might just be using a template

Secondly, how did you get your SN?
If you bought it, your seller didn't cross off it, aka someone else se'd it already.
I recommend you eBay it.

I got my SN from Mothered.

I used the amazon recipt.

I'm gonna try again with a new email (maybe new adress)

I added you on discord.

Sorry for late reply. I accepted the discord request.

Mothered shouldnt give you a used SN, so that's crossed off.

If you haven't used an email address before, it shouldn't be a problem, same with address.

But, the main problem is that you used an Amazon reciept.

Logitech, being beginners-friendly, actually does not allow Amazon reciepts. If you are from the us, use bestbuy or Walmart. If you are from the UK, use Curry's or game.
