[2019] Attempted to pay Ubisoft money, and they don't want it.

I have a free standard version of The Division 2 (offered to provide screenshots and receipts or anything additionally needed) from purchasing an RX580 2/24/19, and decided since Anthem was such a bust I would reach out to Ubisoft about upgrading that free standard copy to a Gold version allowing me to start playing today.

So I'd be paying Ubisoft 40$ they wouldn't normally have gotten from me in anyway shape or form, and to my surprise they wouldn't take my money. My basically FREE money they refused to take I offered to do it in anyway that would reach the end goal and was simply told this would not be possible. This seems a bit strange to me that a company would rather not make additional money they weren't going to originally... I am hoping that this post reaches the proper eyes so maybe this is something that can be taken a look at, it seems strange to not allow "upgrades" of packages (I was informed even a normal purchase would also not be able to do this and that is absurd to me
