Private Customer Forced to Get Importer’s Code

I paid for my full SHEIN order, but Buffalo is refusing to deliver my parcel unless I apply for an importer’s code. I am a private individual, not a business. My parcel is being held and delayed for no valid reason. This has caused stress, wasted time, and uncer*****y. I want my parcel released and delivered immediately. I also have already contacted SARS and was told private imports do not require a personal importer’s code
