Jifan Parcel Not Delivered – Tracking Not Working, Refund Request

I am writing regarding a parcel I sent through Jifan’s parcel service in January 2026 with tracking number JFGJ171595535CN. Despite the time that has passed, the package has never arrived at my home address, and when I try to track it online, I only receive an error message instead of updated tracking information. I have repeatedly tried to contact Jifan by phone and email about this issue, but I have not received any response. I find it unacceptable that my shipment is missing and that there is no communication or support from customer service. Given that the package has not been delivered and I cannot obtain any useful tracking information, I request a full refund for this shipment as soon as possible.
