Canada Post

IF I COULD GIVE A ZERO I WOULD.
I had placed 3 SEPARATE orders from 3 SEPARATE companies at 3 SEPARATE times within the past 4 weeks. As of December 14^th, all 3 items were simultaneously marked as «out for delivery» which led me to assume that their arrival would shortly follow.
One of these items is a textbook for a class which is now already in its second week… I am falling behind and my school grades could be affected which could end up costing me MUCH more than just a textbook; if I fail this course that is anther $ 700 that I will never see again all because of Canada Post.
It is now the 18^th and I still do not have my items, which are are still marked as «out for delivery». I contacted Canada Post, waited 20 minutes for them to pick up, notified them of my problem and was placed on hold for another 10 minutes. When the representative returned I was told that they do not have ANY information regarding my orders or their whereabouts. I inquired as to if they might sitting on a delivery truck somewhere and they said that they don’t usually leave products in a truck overnight.
SO if my 3 SEPARATE orders are not at the post office or on a truck… how exactly can they be out for delivery!!! FURTHERMORE, I was told that I would have to contact all 3 sellers myself in order have THEM call because I am legally «not allowed to open a complaint ticket»; why would a company who ALREADY HAS MY MONEY bother contacting Canada Post… this is UNFAIR FOR THE SHOPPER.
Canada Post managed to lose ALL THREE of my orders, placed at completely different times from various companies/​locations and will not take ownership of it even though they were the last company to physical have the item.
I did NOT choose Canada Post myself and I NEVER EVER EVER EVER will. Please note the emphasis in EVER***
