AliExpress also ****

Good day I'm very disappointed, on the 13 January 2025 I purchased a computer part from AliExpress, and received a order I'd number (***). The 15 January 2025 I received an shipping update, with the tracking number (***) through FedEx IP. So yesterday the 22 January 2025 I cantacted FedEx they told me that they have this problem with AliExpress, they have the same tracking number but for engine part for a company in Pretoria. My shipping status says it's delivered and I received nothing. Please help
