Hi.I'm new too.Was thinking to sub a 90days game time using official site but due to region problem i can't seem to do that too.After that I used the site ''Offgamer.com'' which i used to purchase digital cards and games for other mmo.You probably can try this too.Select credit card/debit payment , verify the OTP(security) on your phone and you get your digital code in 1-5mins. its very safe and fast.
