I don't know what the hell is going on with the Post Office but it is ridiculous! I am tired of being lied to by my local postal service but I will report everybody if my package is not redelivered tomorrow 12/30/2020. It's a damn shame!!! Bad enough it didn't arrive before Christmas now here it is my Daughter Birthday was yesterday, received text from postal service saying package was delivered and it wasn't was suppose to be redelivered today and it hasn't wtf!!!


I ordered something September 12 an they telling me it can't be found but the tracking saying its here in buffalo ...i look up for what location it would be at ...they still telling me they don't know where its at......never us them again...but they better tell me something


Our mail has not been picked up and when trying to reach someone/anyone at the local post office it is impossible. Our postal carrier Joe Hughes retired and Jeanne was covering thru end of year. Now the permanent associate is no where to be found. We are a business and can not afford to have our mail skipped from day to day. Please have someone address this issue. Than k you.
