Even long before the virus, anything I send through this post office is never delivered on time. I could pay extra to make sure my gift arrives on time for a birthday, etc. and you can be sure it won't arrive on time. When the person in that town goes to the post office to inquire about said box I sent, he is spoken to so rudely like he means nothing and is beneath him. I am very disappointed with this post office t

I am sick and tired of recieving all my neighbors mail and not my own. The government notified me that I received my stimulus check and I didn't. It was in my neighbors mailbox. This caous has to stop. I have been dealing with this for years! It MUST STOP!
