We are having trouble getting our mail delivered in a timely fashion following a hold mail. This happened last time and the excuse was carrier was on vacation and sub did not see it. Well here we are again....no mail that was supposed to be delivered today.

Throughout the past 9 years we have almost made it a ritual they all the neighbors on our street get together and exchange mail for the proper address> Anyway now I ordered YET ANOTHER item and YET AGAIN it says it was delivered and I have NEVER seen it. I spoke with ebay they are telling me "sorry Sir it shows it was delivered call your post office" I called the post office and I get " Sorry Sir it shows it was delivered file with ebay" YA GREAT I kept going back and forth with a fella and being told " it shows it was dropped off, gps shows it was dropped off, it states it was dropped off" But funny no matter how many times he said amazingly enough IT STILL NEVER APPEARED in my mail box ????????? Not sure what to do at this point.

Can honestly say I usually never have a problem with this post office but I called to ask a question and before I could finish what I was asking I was interrupted and when she talked to me it was like I was an impatient child.. I could understand if I was being rude or something but I was trying to explain what my email was telling me and ask if this was just a mix up again and I got a lot of sass from her. Just hope this isn’t a normal for this post office.
