I called in for a refund exactly a week ago and was told it would be done in 3-5 days, been playing (when the game works) on and off since then and since I hadn't gotten a refund yet I kind of assumed they decided I played too much to deserve a refund, which is fair enough.
Just got a refund posted this afternoon though, into my PSN wallet. I can still launch driveclub although I expect that'll stop working soon enough. Online store and PS4 storefront both won't let me buy the full $60 version saying I already own it, but both will let me buy the $50 PS+ version still (or at least add to cart).
Anyways just a heads up for anyone else who asked for a refund, it just sorta appears in your wallet, nothing in transaction history as far as I can tell.
