Very Bad Service from Buffalo Logistics.... Goods Still not Delivered... Unable to contact them

Very bad service and unreachable. I have placed an order on shein which was supposed to be delivered by Buffalo Logistics. They have tried once to deliver, however I was not advised of the delivery date and was unavailable to receive my order. I tried calling Buffalo logistics over 10 times, I got no response and was not assisted. To date I still have not received my order. I emailed their customer support, I didn't get any help. Fortunately I was refunded from Shein but I have lost out on my custom fees that I paid to Buffalo logistics.
