You cannot cancel an order by posting to the forum.  You will need to call Dell customer support.  
I tried to look at support emails but spent ~3 hours not finding a customer support email. How the heck do I cancel? I'm afraid it'll go into production when I sleep and it's driving me crazy! Let me cancel please. At this time the order is still being confirmed, can you please know that at this point I want to cancel. Hopefully when I wake up it's not in production already, because if it is it'll likely just be returned when it's eventually sent to me. I'm not looking to change my order, I'm looking to cancel my order. Many reasons why, multiple of which can't be changed, nor fixed. Don't get me to explain (not willing) or you will waste everyone's time: I'm not likely to change my mind. Sleep deprived customer at 3:25 am Sunday 8/22/21.
