Neighbors mail was delivered to me, where is my mail? They don't answer phone! Hello anyone out there!! According to their hours they should be open. Thanks!!


I need to mail out quite a few mailers but need to know the price per Sheet. Sheet would be folded in 3rds, (8x10)


this post office doesn't answer their phone


Multiple calls from my creditors for mail i dropped off at the Sylmar location has not been delivered. When I went to drop off replacement checks I found the drop off box had so much mail in it that the letters were not dropping down. This is election week in Los Angeles and San Fernando. The box closest to Glenoaks Blvd in front of the Sylmar Post Office has bee full for at least 2 weeks. How are the absentee ballots going to be handled since they will not be post marked or received by elections officials on time?
