Welcome to the forums. Do NOT send a third I-129f package. You have at least one at the lockbox already. Nothing happens as fast as you want regarding US immigration. Yes, waiting is hard.......but having multiple duplicate petitions in the system will be a big, big headache and cost. Instead, keep studying the process and the forms needed in the next steps. Becoming an "A" student will make the whole process much easier. Good luck. Keep us updated. Your experience will be valuable to those who follow in your footsteps.
Note: Never send anything to USCIS without a proper tracking number.
