Dell has the worst customer service EVER

EVER!

i've been on the phone now, (still on) for over 3 hours now and still I'm getting passed around from one customer service rep to another. I ordered a Samsung 51 inch tv from a  sales super because I was concerned I was not gong to get good service. The super tells me there are over 730 tv's in stock. I received an email saying it was shipped and another email 10 hours ago saying it was delayed until the 31st. I've talked to over 11 people during the last 3 hours, including 5 sales and customer service supervisors and have been tossed around mercilessly. Each one of them assuring me that the next person will be more efficacious than the last in solving my problem. One of them told me that there was another promotion I should have been contacted about, a 60 inch plasma for $849 with a $500.00 gift card.... but unfortunately, since they didn't call me and it was no longer available, I was . Ok, so I've been lied to about how many tvs there were by the original sales supervisor, spent 3 hours being tossed around (most of which I was on hold for) , told that my order had been canceled, told that they were wrong about that, my gift card was only $150 instead of $300 (oops they were wrong about that too), and told that they weren't going to do anything further despite the fact they have loused up everything about this order. Completely    horrible customer service. You took my money and gave me nothing in return but an empty promise and a realization that  I would never receive my tv or anything that resembles customer service. Sheer incompetence of the highest order. Dell would be better off hiring employees than these . If you can't tell, I'm VERY, VERY ANGRY and I will happily blow this up all over social media.
