JCEX Package Marked Delivered but Not Received

I placed an order for an electronic product which was shipped with Jcex under tracking number JCEZI1000014966YQ. According to the tracking page, the package is marked as “DELIVERED” on September 13 to the address 532 NW 173 Street, but I did not receive any package at this address. On the stated delivery date I was at this address and no courier came, no one rang the bell and no notice was left at my door. I also checked with the people living at the same address and with my neighbors, and no one received a package on my behalf. Despite the “DELIVERED” status in the system, the product is not in my possession. Because I have paid for this order and never received it, I request that Jcex conduct a detailed investigation of where this package was actually delivered and provide me with a full refund as soon as possible. I expect this issue to be resolved promptly, as I should not suffer a loss for a shipment that I never received.
