Poor service I want my money back

In August 2025 I received a wrong receipt for someone who had purchased medical equipment when I had purchased hair mind you it was my first time purchasing on shein however I received the most terrible service from buffalo. They kept on insisting that I have received my product and on their system it shows that I have received I should check with family or neighbors when I stay in an estate. Next thing buffalo says no it was a system error my product is scheduled for delivery which never came I asked for my refund and was told I need to contact shein which I had already done shein said buffalo needs to refund me because my hair was dispatched correctly to them. As a first time user buffalo logistics in South Africa is terrible and shouldn't operate they take people for a ride including their management. Later on Rebbeca claims to be the manager but never delivered on her word instead she ghosted me like her junior employees. My order number is BUFZA7DF00373TPYQ kindly please do the right thing because you know buffalo is wrong
