20 twink leveling

if you have a vet twink, so you payed for a month of game time, geared your twink and waited tell the time ran out. would you be able to turn xp back on when your time runs out and not level up in BGs when your account is free to play

No, you need to turn your XP on right before your sub ends. Then, after your Sub ends, wait 1-2 hours or so to clear your Sub. If you do not wait for sub to end (It should say (Inactive) on all your 21+ characters), you will level in your next BG.

1. If you turn off XP before your sub ends, and you need it turned back on, thats a ticket.
2. If you leveled to 21 after your sub ran out, that's a ticket.

Typically, both are solved in maybe a few days if you put in a proper ticket ( e.g. don't sperg out and have bad grammar/manners).

But yeah, turn on xp before sub ends, and wait a bit afterwards
