Items removed/****** from my parcel.

I'm referring to this parcel BUFZA***YQ, I was informed that 4 items missing and was told by Future that I can request a refund from SHEIN. SHEIN doesn't want to refund me for the missing items as they say the parcel was in order when it left them. So who is going to be accountable for this now?? You can CLEARLY see that the packaging was only ripped at the top, and not damaged anywhere else! Someone clearly tampered with it and removed items!!! I have spent close to 2 hours this week calling Buffalo Logistics, trying to get them to respond. IF I'm lucky enough that someone actually answers the phone. I'm kept on hold for 12-20min!!
