As a board member of Sunridge Terrace Condominiums at 4514 3rd St; La Mesa 91941 - I have received numerous complaints from our residents regarding our mail delivery since Denise Lorenz retired the end of November. Mail is not placed in the appropriate boxes, highly sensitive mail (social security info) is put in the wrong box. The past two days I have received mail in my box addressed to Units 1, 4, 9, and 15 - my box is 20! If this was a one-time mistake I could understand. Unfortunately it's ongoing. Please assure us that our mail will be handled securely and accurately, especially with end of year tax documents containing personal.information will be arriving. Thank you for your attention to this request, as I do expect accuracy and care of mail delivery from a government agency.
