Talking to Amazon UK customer services. Amazon will accept returns for Cyberpunk 2077 upon software investigation.
Going from their returns policy;
It does leave the confusion which some people will want clarifying. As it states in their policy about new items should be returned unused and undamaged. Of course, players over the world didn’t know what kind of shape the PS4 or Xbox One versions will be like. Once you unseal the game and install, download and start playing. The problems obviously occur, which leads to our confusion about returning to Amazon and what their stance is.
Amazon Customer services said “If the software is defective you will need to return the item to us so this can be investigated.”
We are still waiting for response from GAME UK, as we earlier reported GAME Espana will not be offering refunds.
