Waiting for a month for an International Delivery

The service from Buffalo International Logistics is so pathetic that I don't even want to give them one star. I ordered a parcel from Shein and paid the Tax the same day I received the email. It has now been a month and I have still not received my parcel. I had to follow up various time to be told I have to email the proof of payment, this was done four times, still no parcel. Then I had to pay the VAT again and submit a refund request for the first VAT paid. They stated that the parcel will be delivered within 24 to 48 hours. It has now been a week later and still no parcel. Do this pathetic service I will never use or recommend their service to anyone and won`t ever order from Shein with hem being the courier company.
