Baffalo logistics lost my parcel.

I ordered things from Shein last year October till today Baffalo has not delivered,To make matters worse they even apploaded wrong parcel into my profile on the 04th of November 2023.They don't bother updating me I am the one who calls them everyday and they keep on saying they will escalate the matter or the matter is Still under investigation.I am tired of their stories I just need my refund or my parcel.
