OH god.
Last house was on the cusp of 3 towns/zip codes. Huntington, Huntington Manor, Huntington Station.
If you did not match the zip/town name exactly I would not get the mail.
IRS froze all my assets once, they tried to send me an audit notice which was returned to them. Living in the house for a few years and my mortgage statements stop showing up for 6-7 months then just start up again. Daughters Birth Certificate never arrives, etc... etc... etc...
I called one time to complain, supervisor says she knows my area is a problem, they changed the system and sent out letters to my area to inform us there may be an issue with delivery. Told her I guess I never got it.
After 1/3 hour of "discussion" she tells me the only way she may be able to figure it out is if "I get her an envelope from a piece of mail that I did not get"
