I have had to complain to the Postmaster/Manager of this station before about not receiving my mail. Now things have gotten worse. Since COVID I do not mind if the postal person leaves or throws my mail upon the front porch, but my problem is my mail is left at the home of other people whom I do not know and do not live on my block. Thus I receive my mail through them many times and I usually receive it on a Sunday. I have time sensitive mail sent to me that I receive late, if at all and thus I am not able to respond in a timely manner. I no longer receive my mail through the week, it is only on a Sunday (if then). I now have to write a letter to this manager and the Postmaster/manager at the main post office. This is ridiculous.
