Wow. Just wow (sarcastic of course)

If i could give 0 stars I would. The absolute horrible experience I have had with this company in the last 24 hours is mind blowing. Everything from their tracking, communication with the customer and atrocious app. First of all, it seemed as if Shein was more up to date in knowing where my package was, the buffalo app and website always seemed to be 2 steps behind. 2nd problem was, on the 3rd of September I received a message saying that my package is being dispatched and I will receive it before 4 September (so in less than 24 hours). Moments later I received a WhatsApp from them saying my package has been dispatched and i will receive it between 24-48 hours. Sooo which message gives me the real ETA? Plot twist, both of them are wrong (so far). So like the idiot I am, I take the 3rd of September off work so that I can receive my package. Only by 19:00 I receive a message from SHEIN - not even buffalo, saying my package has been returned to the warehouse because they gave it to the wrong courier (please take note of this). Confused, I try to message them the next morning through the app. And what a wild ride! First off all, you need to jump through 20 different hoops to reach an agent. I manage to get through to them, where they send me 1 message and then end the conversation before I can reply. So I have to start the whole process again to reach a human. Finally after 4 different agents I reached an agent saying they couldnt find my address on google maps so they sent my package back. Now, 2 points here: 1 they have successfully delivered my package to my current location numerous times in the past, so what changed? 2: why not contact me the day of saying they cant find my address. So at this point they ask for my address, which I give again, but not before I was once more disconnected from the agent! So 5 minutes later I reach another agent. Manage to give my address, and was told my order will arrive in 72 hours. But ofcourse once again I received a confusing WhatsApp saying they have shipped my parcel (according to the app the parcel is still at the warehouse) and I will receive it within 24-48 hours. Sooo again which one is it? Has my parcel been shipp, is it still at the warehouse. In what time frame am I to receive it? I never complain on my twitch channel but after this experience I might just go on my first ever scathing rant. Seeing as im also no longer able to use the contact us function
