Customer service agent I spoke with barely spoke English and didn't seem to have any idea what I was talking about regarding a simple mail hold and address change. It's a very time sensitive matter, and she promised me a call back after she could "check the system," but I haven't heard from anyone.
Impossible to reach anyone to begin with, the phone is permanently busy it seems.
Service is slow and inadequate in store as well.
But, what would you expect from a government run agency?
