Accidentally purchased two keys, can i get a refund for one of them?

I feel like an idiot. I usually pay for stuff via PayPal, but I didn't remember getting to the PayPal confirmation screen the first time I went through paying for the software, and to add to that, I somehow ended up back on the purchase screen, so I figured I just hadn't gotten to confirming the order yet, especially since it was still in my cart. So I just went ahead and ordered again, went through everything and actually fully completed it this time, got to the PayPal confirmation screen and everything, and now the item has obviously disappeared from my cart. Went to check my balance and noticed I was way lower than I anticipated, so I checked my account activity and it turns out I had paid for two keys. Also figured out how to check the keys tied to my email and sure enough, two keys. I only need one key.

Is there a way I can get a refund and deactivation for one of the keys? I emailed the support email and got an automated response. Tried looking for a refund support email and have not had any luck there, so I came here.
