Re: Dead Space 2 Collector's Edition DLC

What about in 2023? I can’t seem to get any confirmation online anywhere if these codes are still good. There is no expiration date on the vouchers. I’ve tried two and PSN only annoyingly says it’s “invalid” after taking me to a screen to confirm whether I want to redeem the CE content. So, were they invalid cuz they were used and I got unlucky, or were they invalid because they have a back door expiration date? It doesn’t tell me. EA rep had no idea what I was asking and Sony told me to F myself. 

Can anyone confirm that an unused CE code for Dead Space 2 will redeem in 2023 for the PS3?
