how its works silly as it is
your escrow coins are locked away if your preferred or free to play ( subs obviously dont have lock )
your cap on f2p is 350 k credits, it does not fill back up on its own you need escrow token which some people overprice alot but if you got into the gtn and type escrow they should come up unless they all have been purchased
when your at the max 350k credits and you use a token yes it will add it on top of what you got... so if you have 350k credits and you use a 150k escrow token you will have total credits of 500k till you use them but it will always cap out at 350 k.
so for example if you had the 350k right and your used the 150k escrow you have the 500k. The 500k is able to be traded but soon as you spend it or trade it you will build up to the 350 k credit cap until you use another escrow token
tokens come in 50k, 150k and 600k and can also be purchased on the cartel market... Also if you cant find them you can hit "i" or what ever you have your inventory button set at then go over to the currency tab and youll see how many credits you have in escrow exactly the i believe it has a button beside it to access escrow credits
and you can find it that way
inventory pic will put up more later

hopefully this helped you or any others
