Had to have the lock changed on my mail box and paid the $40 fee 9 business days ago. I called today and she told me shes not sure how long it will take it's whenever they can get someone out probably next week. When asked if my mail is on hold at the post office I was told it is still going into the box because I didn't put a hold card at the office. "Probaly next week" will be about 13 business days. This is unexceptable.
