Your best bet would be to approach the supplier of your case (who you purchased it from) and ask them about finding a replacement.
You could also try opening a support query with Corsair, It is highly likely that they will be able to ship to your address, you may just have to pay shipping costs.
Failing that, the last things to try would be to check your local buy and sell websites, talk to any local computer stock suppliers about ordering some for you or see if you have a friend or families address that Corsair can ship to who can then forward it on.
