Buffalo International Logistics poor service and lack of communication

REFERECE NUMBER-BUFZA***YQ -I placed my order on May 19 with Shein and it was processed. I paid the customs duties. However, I am now having issues with your logistics. It appears that they do not want to deliver my package because they keep updating the system with false information, claiming that the office was closed, incorrectly allocated, or wrong address. I have verified that my phone number and address are correct, and they did not even attempt to contact me, which surprises me. They also said that I should contact my supplier (Shein )what does this mean. Please help. I'm constantly waiting for them, but they never seem to show up. To my astonishment, I've placed an order with Shein previously, and I received my package without any issues. Why are they having trouble delivering my second package?It's unfortunate that I didn't consider checking them before making an order with Shein because I was unaware that they were using them as their logistics. I'm always receiving massages saying that your order will arrive in 48 hours. the system continues to display "out of delivery." They say my address is incorrect, so I checked it again and updated it. I've tried to talk to the South African warehouse about sending my own courier, but they've refused, saying they don't have that choice. The lady l contacted has since told me that she will escalate the matter
