Delivery failure

I placed an order on Shein 5th of November 2021 and I have followed every instruction to the latter. The payments done right. On time. And yesterday I get an email message saying: I place my order on Shein and now I received this email.

Dear customer, It is a pity that your order ************X tracking number ************ delivery has attempted failure.The main reason is due to insufficient address/phone number/no one at home when delivery etc.Please kindly contact your local carrier to get the parcel soon in case it return to sender. We are always at your service if you need any help.

Been trying to call the offices on ***. No luck as I want to talk to the agent/customer consultant. Their WhatsApp number too no help. Two ticks to show message went through. But no communications.
