Poor experience and disappointment

I ordered on the 17th of March and then on 19th I payed customs for my parcel on the 3rd of April status changed and client received yet I didn't get any parcel and I didn't get any call saying I must come and collect it and my email and phone number are correct when I write Logistics an email they say I should contact my supplier and at shein they say they won't refund me because it stated on their side that Client received on the other side Buffalo logistics doesn't want to take accountability they say my order get lost i should ask for refund from shein.
