Appreciated for your escalation.  It's been fourth time delay.  Suppose it should be received today and however, it got delay for another week with the order status.   
I have purchased Dell 34" Curved USB-C Monitor. However, the shipping date has been delayed again and again.  It's the 3rd time update, and it's a month already from my purchased date.   There's no one I can talk with except keep checking the order status online, and there's no option for live chat at order support area. Appreciated someone let me know what happens to my order.  I need more details before I decide to cancel it or not.   Thanks.
