Parcel CP462330538CN. It was no updates since March 4. When the transporter will deliver my order?

LM717686180CN. Tracking said parcel on plane and plane arrived on July 29, 2021. Then it stated again that plane arrived on July 31, 2021. Then, tracking stopped. ePacket can be tracked on Canada Post if it has been handed to Canada Post for Customs clearing and local delivering. But Canada Post tracking shows: still waiting for parcel to arrive. Usual ePacket tracking should show the Canadian city that parcel arrived at and also that it was handed to Canada Post or local receiving carrier, if parcel has truly arrived in Canada, and not just plane has landed. Today is August 17, more than 2 weeks after plane has landed. But still no information of the parcel whereabout. Where is my parcel? Is it still stuck in airport in China? What can I do now? I have already alerted Seller. But Seller kept saying just wait. What should Seller do? Is parcel lost?

My parcel has not updated since december 1, with the message "Guangzhou City, delivered to the carrier." This, along with some other people with similar message, has led me to believe that my parcel is on a boat and not a plane like usual, is there any way I can track this parcel more accurately so that I can be assured that it will arrive? Thanks!
