Extreme delay in delivery

This is the worst courier services ever. I ordered a Shein parcel. The driver was suppose to deliver on 2 September. As it happens he phoned me at a time when I was in a meeting. Only for that few minutes. Then after an hour I whatsapp back to say that I am available. I tried to make several time contact with Buffalo with no joy. They did not even try to make contact with me the next day for delivery. Then when I sent an email to inform them to *** came back undelivered with some Chinese message. Which I had to translate. Then the message said that their mailbox is full and the message is undelivered. So why giving me an email address that is not working. Their link to complete a change of address didn't work initially and I notified them via whatsap. Eventually the link worked. So I changed the address and according to that message the next attempt would be to deliver then on 4 September. It is now 5 September and still now delivery. After a long waiting time to eventully got hold of them they said that my parcel has been sent back to relable and that takes 72 working hours! And I need now to pay extra delivery fee which is unacceptable just because for that short space of time I was not available. They didn't even try to deliver the next day.
