Horrible experience with horrible service

I placed an order from shein on 6 April and I paid customs on time. I was expecting my order on 13 and the order did not arrive and they send a message that it will be delayed by 3-5 days on 18 I call them again they apologized and said they will send it on 23 I did not receive my order again. I ve been calling them and emailing them day and night they don’t respond to my emails. And when I called they say different stories I called last week Friday they said I will receive my order on 29 April which was yesterday and I did not receive the parcel. On the 30 I decided to hire a car and go and check at pdp logistics since they working together and they said my order is in eastern cape and am staying in Kzn. I came back with nothing. When I get home I decided to call buffalo again they confirm that my order is with third party they can’t trace it. I called after 30 minutes again because the person who was attending me was so rude. I spoke to some guy he said my parcel is here in KZn they called pdp to come and collect but they did not come. I asked buffalo to tell me where is their warehouse here in durban they said that is confidential they can’t disclose that to me. I am graduating on the 7 which is next week and I need to wear these clothes my whole outfit is there but there is nothing they can do. Such a horrible experience I will never order anything online or use buffalo logistics
