And since i dont feel like doing math to figure out your exact subscription date (as in the monthly day), like i said you should get it on the day your account was subscribed to STO. I'm not talkin about the 600 day vet rewards, I only answered about the c-store points.
Did you have your Lifetime activated from the very start? Because if not, the day you got Lifetime would be your starting date, which isn't necessarily 669 days ago.
(For example, my account says 670 days, but I changed my subscription plan after a year, and the last time I changed it was actually like the 3rd of the month, so I got my stipend several days ago.)
Also, these sort of things tend to be done on an automated timer that probably runs just once a day, so I would give it up to 24 hours as it would depend on your relative time zone to whatever the account server is using.
I haven't recieved my Stippend yet either, but i'm at 694 days but not willing to sit down with a calander and count it out lol
As for the VA token as a 600 day vet reward, yeah that IS kind of crap. They stated that if you hit VA and used the free token they gave you then, you're not eligible for the Vet Reward Token. So basically most people wouldn't be getting one.... at all.... So for not only EARNING a free ship, but now being a Loyal Customer for 600 days, Cryptic has given a proverbial finger to the fans. This means that those unlucky enough to have missed the 500 day emblems but were VA before 600 have are missing out on TWO different vet rewards.
Personally i'd love to use my vet reward to get a new defiant Retrofit since the Sau Paulo refit didn't live up to any of the hype and since earned it with out C-points, i'm not able to reclaim it.
