Do China Post deliver their own mail in maybe China Post vehicles or do the arrange for other company couriers to deliver? Is it a China Post truck/car or common vehicles such as ebikes etc? Thanks

One of my orders is listed as delivered but I haven'r recive my package. I already check with local post office and told me that they dont deliver China Post package anymora, that another company its delivering in Mexico, please would you tell me wich courier does deliver in Mexico so I can check about my package

I'm waiting for my package but the tracking number says it's been delivered, with what courier company have they used to deliver it
