Poor customer and delivery service

I orders Shein ont the 5th of November, by the 8th of November the order was assigned to imile. Shortly after that, I paid taxes and then recieved on the 11th of Nov on my status that delivery will be delayed by 5-7 working days due to flight shortages, and then on the 19th of Nov that my order will be leaving before the 23rd and now the 22nd of Nov I got a new update that it will be leaving before the 28th of Nov. This is utter bull****, I am so ****ed off and the fact that I can't get a contract number to phone imile ****es me off even more You do not respond to my emails, and your WhatsApp line communication is pathetic. The Taxes I paid was outrageous and then having to wait for so long is absolutely unacceptable. This is by far the worst service iever had ever. It is impossible that there is such a big delay (3 weeks) in flights. What the he'll is going on??????
