Information Refund Steam

If by repay you mean refound, then yes... Even tho the game its broken theyre trying to fix it, but its up to you if you want to keep it... But in your case I dont think you get a refund, Steam's pilicies are very clear in that subject...

From what I've heard so far, they might still refund you even if you exceed the limits if they think your request is reasonable (which, of course, is subjective but still). With a game like Arkham Knight, I think there might be a chance that you get the refund.

But I have no personal experience with it, so it's just what I've gathered from reading about it here and there ;)

Just try and hope they will refund it, there's nothing to lose.

wait untill its fixed

you can try and get a refund, the worst case scenario is that they deny it

I'm pretty sure they'll allow it.

I had refunded 2 games that exceeded 2 weeks and 2 hours rule, and the reason was because it got better discount, try if you want, but I can't guarantee it. And anyway if you do it a lot less likely they will refund it for you.

They have announced stuff for it, after they took it down for fixing.
