Buffalo international logistics

After waiting for a month and a half for my SHEIN order and making numerous phone calls to Buffalo. No feedback was received regarding where my order is. On my 3rd escalation I made contact with one of their driver through a friend. They checked for my order and they advised that my order was moved from their warehouse to a third party for delivery. When I called the third party, they confirmed that my order was booked to be delivered to them on a certain date. Till the day I called, they had not received it. What’s upsetting about this experience is that when I call Buffalo they keep on telling me that they have escalated my issue for investigation. They don’t communicate with their clients for updates. When you call them after waiting for close to an hour to get an agent, they will only tell you the same feedback they gave you the last time you called. No sense of empathy for the customer whatsoever. No client oriented solutions. Just systematic feedback. When I asked for a refund, I completed the refund letter and sent out my bank statement as proof of payment. Of which I don’t understand why I had to provide proof of payment since it shows on their side that I paid Tax and they are aware that they lost my order. Now I need to go through so much paper work to get my money back for the order the lost. Till today, no refund has been made. I called them today regarding my refund and now they are saying they can’t accept my bank statement as proof of payment. No sense of empathy for me as a customer and positive feedback from the agent. Overall experience, I will never order with SHEIN again because they keep on using this ****pie logistics company who lack accountability and customer centricity.
