My last monthly stipend was received on 4/4/14 in the amount of 500 cartel coins, appropriately labeled as subscriber perk.
That is the last subscriber perk I received save for the "in-game reward" bonus of 1,000 coins that was offered (to my understanding) separately from the normal perk of 500 coins.
I imagine, however, that this is something we all need to be calling Customer Service about, yes? -bp
An update: I called in to Customer Service to resolve this issue and it was handled quite timely and professionally. Resolved in a matter of 16 minutes (because it required escalation). So, if you're having issues, I highly recommend calling in. -bp
