No mail/ extremely frustrated

I have not received any mail since December 30, 2024 and it was one letter. Mail that was sent to me mid-November, mid-December and even the past few weeks keeps showing on the MyMail app as enroute then delivered and yet, nothing in my mailbox. I have been on the phone with Canada Post for 3 weeks. No one can give me an answer. The depot says nothing for me there and sends me back to the customer service line. I kid you not the customer service supervisor has been calling me each day to ask if I've gotten mail! What exactly are they doing to answer me as to where my mail actually is? One hand does not know what the other is doing. I'm not even receiving flyers that's how bad this is. No mail and this means cancelling cards that were already mailed to me. I'm at my wits end. Does anyone have any other suggestions from their dealings with this agency? I pursued a claim with the CP ombudsman but they shut it down because Canada post still has my ticket open. For service they are not delivering and can't give me any answers for. This is crazy!
