amiga_jboy: I was able to get a refund.
I'll describe the process of my refund. (For your reference)
Purchased Cyberpunk2077 from GOG using Paypal on December 10.
↓
Requested refund from GOG support on Dec. 18.
↓
On the same day, GOG support asked me if I wanted to use my wallet. I replied that I would like to be reimbursed in full to my Paypal account.
↓
Waited for reply from GOG support.
↓
On December 23, I used Paypal's "Report a Problem" to send an email to GOG support.
At that time, I created and attached a pdf document with the email images we exchanged and the reason for the refund.
(The pdf is so that people other than GOG support can understand the reason for the refund. Just in case.)
↓
On December 24, I received an email from GOG support saying that they had refunded my money.
At the same time, I also received an email from Paypal saying I was refunded.
This is ridiculous.
There are still people that requested a refund way earlier than the 18th and they haven't even got a reply yet, myself included.
