Aurora R12, replacement

So my story begins here I purchased a Dell Alienware laptop a year ago I received a laptop that was not working properly so a technician came and long story short the laptop had to be replaced, which Dell did a good job with. I proceeded to build my lovely Dell setup and purchased a monitor and Aurora R12. now a few weeks ago I received my Aurora R12 which I replaced with my old work desktop and boom straight out the box it was a piece of trash. the Aurora R12 does not work. so I contacted tech support and everyone I needed to and was told wait 3 days we will find a replacement 3 days later nothing, So I talked to Dell support again and was told wait 3 more days again. keep in mind I need this computer for work this is how I make MONEY! 7 days later now Dell support tell me hey we can’t replace you computer because we don’t have anything similar. so now I speak to many supervisors many reps constantly hung up on and dropped calls over and over. So Dell offers me a refund so i think sure why not but then here’s the bad part refund can only start once they get back the trash they sent me so 5-7 days and then refund processing 5-10 days and for me to research another computer and buy 1 day and 5-7 days for Dell to ship. Now that’s a big wait time and Dell has already wasted so much of my time! So I went on the Dell outlet and viewed some of the refurbished desktops and boom I clearly see computers that have similar configuration to my computer yet Dell is telling me they cannot replace my computer. I even offered to pay the price difference on the new unit that is how badly I want my product but nope Dell treats there loyal fan customer like trash. I am still struggling to have my computer replace! Someone help me!
