Also have the same issue. Got my Cartel Coins for the authenticator 2 days ago but haven't received my monthly sub grant. I would put in a ticket but last time I did that I had to wait 10 days and only got a generic copy paste response, so I try to avoid tickets as much as possible.
Update: Just posted a ticket, let's hope it doesn't take them too long to repond.
Update: Just had a live chat with a droid that "is a night owl"
. There is a short delay in this months Cartel Coins and should be here in 7-10 days. First time I actually spoke to one of the droids and was pleasantly surprised that they actually had the personality programmes installed and are hard workers ( ticket responded to at 04:30am uk time)
