Review More Deplorable service

Here we go again. In early November I mailed several birthday cards to my loved ones, and enclosed all the cards in one envelope, and almost 2 months later this envelope HAS NOT been delivered.
The postal service in Cagayan de Oro should be ashamed of the way they handle the mail.
If I thought an investigation would help I would contact the proper authorities, but I fear that they would respond as well as the post office.
I only hope that the post office in Cagayan de Oro finally gets their act together and does their job. Somehow I have my doubts.
