Shein — it has been 15 days now from i placed an order but still it doesn't delivered.

I placed my order on 12th may 2020 and it has been 15 days now still i don't received my order, even in tracking page it doesn't updated after 18th may 2020. My tacking number is [protected].
Even i try to get a customer support from shein but their customer service is very poor. I try to assign my complaint by live chat in this they can't even reply my message and after some time it automatically shows that my problem is solved. My live chat ticket id is 35327890.
Then i try to solve my problem through call and i called on shein customer care number 100 times from 22nd may 2020 it always show our manual service are busy.
Then i registered my complaint on 23rd may 2020 at resolver, my case id is res8802878. And it has been 4 days now i didn't receive any update from there.
I am soo much frustrated with this now, what can i do now my order is already pain.
