8 days, no delivery No response on my numerous enquiries

On Monday 13 April I received a whatsapp message from iMile that my 2x Shein orders will be delivered within 48 hours. By Wednesday afternoon, no delivery was made, so I phoned the call centre number, but they already left the office. SO I logged complaint for the 2x packages on their whatsapp. The tracking status was updated to read 'incorrect number'. On Thursday I phoned the call center, only to be told that the "incorrect number 'update was a system error, and when I asked but why is it not delivered, as your message stated within 48 hours, I was told that that was a system error as well, but I can be assured that even though they have 5 working days to deliver, my packages will be delivered on Friday. Later on Thursday, I received an email from a Tristan Douman, who informed me that the driver could not reach me, this being the reason they did not deliver, and I should send them an alternative contact number. I responded asking to know when the driver contacted me, as I have no missed calls, and they in fact have the correct contact number, as I did receive the message that they will deliver in 48 hours. Tristan did not bother to respond on my message, no acknowledgement or any form of communication further to confirm a delivery or anything. Friday came and went, without any delivery. So on Friday I afternoon after 16:00 I phoned the call center again, to find out if my packages will be delivered as promised. The operator informed me that the packages was never sent out the morning, so I can expect it either Saturday or Monday latest. I had my doubts, as I know mostly couriers does not deliver on Saturdays. But I waited, with NO delivery Saturday. Monday during the day, I logged a complaint again, I emailed Tristan again, I phoned the call center again. The call centre said that they will enquire on why the packages are not sent out, and get back to me. I phoned them a couple of hours later again, but was told they are still waiting for a response from the WC warehouse. No reponse on my whatsapp complaint, no response from the email sent to Tristan. So on Monday 20 April, I expedited my delivery on the Shein app, to try and get some response via Shein from iMile. THis morning (Tuesday 21 April) Shein's app status shows the packages are out for delivery, the iMile tracking is updated to show out for delivery. I have not received any calls, and as you can guess, no delivery once again. I phoned the call centre from 16:40 but could not reach anyone there. The phone got cut once, the other time it cut me and went on to a part where I should complete a survey on their service (what a joke) and the other time I held the line waiting on an operator for 11 minutes without response.
