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.
