USPS Customer Service - ABSOLUTELY HORRIBLE!!!!!

The address for this incredibly disgusting post office is: 

19740 JAMAICA AVE
HOLLIS, NY 11423-9997

Listen below to multiple conversations I've had or try to have with the manager of that post office, "Miss Singleton", along with an employee there:

They really do set the gold standard, don't they? And this is why I have very little to NO sympathy for post office employees when they complain about something. I may be generalizing but this is truly appalling.
