I received my order this past weekend.  The computer is working great, just wish it got here with less of a process and in a more timely fashion. For everyone going through the same problems, I would still recommend the same thing I said previously.  Contact DELL-Cares to create a ticket and get it escalated so they can track your progress.  Calling the main dell line didn't do anything for me.  I wish everyone luck with their process, and to Dell. Update your tracking procedures to match the current delays and processes happening during COVID-19 or for any time that their might be issues.  Most people are more accepting if you tell them an accurate truth for the time it will take to receive their products. I assume most people are the same as me, they rather have accurate up front information, even if it shows a delay in services. 
This might be a re-post, sorry if it is. I sent this as a response to someone else's post but it never appeared. I made an order on 4/20/2020 and am having the exact same issue that others have mentioned. They initially said my machine (Alienware Aurora R9) would be delivered by 5/4. On 5/1 I got a notice that my order had been updated to 5/18. I don't mind that the process might be delayed especially with what is going on in the world right now, but I'd like more info on whats delaying it. When I made my order the guy I spoke with said "All of the parts you chose are in stock" I took him at his word and told him to proceed. When I called to check what the delay was, the tech went through all the parts, and said the item that was missing, the power supply... So he said he would put it on a list to be built as soon as the part came in. A few days later I received a notice that my order has shipped. This was on 5/4/2020. It is now 5/7/2020 and the order has not moved. I called on 5/7/2020 to ask about the order and the Dell Rep I spoke with said, it would be delivered by end of day, per FedEx's estimated time, they had until 8:00. Well its Thursday now and FedEx says "Estimated Delivery Date: Pending" I don't mind if the order is being delayed, parts are on back order, or if the dang thing got stuck in customs while being transferred from Mexico to Texas. I just don't like being lied to.I'm on the phone as I type this, because I've had 90 minutes to wait. I've called in four times, and when I do they say they will transfer me to a product delivery specialist, and when they do my call disconnects. Once, fine, things happen, but four times. This is Ridiculous. Update - Tech on the phone is telling me FedEx has not yet scanned the package, and it can take 2 to 3 business days to scan the package, since this order is standard delivery. Standard delivery takes 3 to 5 business days past the shipped date. He told me that FedEx will have an updated message by tomorrow since it was created late Monday night, and 2 to 3 days would put it at the end of today.Time will tell.
Item Shipped, but hasn't left TX - Dell blames FedEx.
