Hi, I just ended mine today. You go in and wait in line. Once at counter you tell them you want to end or cancel your PO Box, male sure you have your 2 keys or I believe they will charge you for them. They will then give you a receipt stating you closed it. If you are due a refund, one will be mailed to you.
You have to go to the counter and speak to customer service person 🙄 🙄
You would have to go to that post office I believe
