Bluetooth Situation

I bought my notebook, the Sentia m3450, about a little more than a year ago. It was supposed to have integrated bluetooth in it, which was a required option. Expecting bluetooth in my notebook, I purchased a Logitech v270 Bluetooth mouse from Alienware. When I received my notebook (several weeks late), there was no trace of the bluetooth, meaning there was no bluetooth module written on the printed order form when I received the package and no bluetooth module in the notebook itself. I called Alienware throughout the past year demanding a solution to this problem. They told me it was a manufacturing problem and that they would get back to me as soon as they found a solution. The problem went on for months until about two months ago I demanded that they send me a bluetooth module that was supposed to be in there in the first place. They sent me the module and I put it in my computer. The problem was that there was no antenna to connect it to in my motherboard in the first place. I complained to Alienware and they had me send in my computer for repairs. They told me to wait two weeks for it to arrive back in my hands. I waited until yesterday, making it four weeks, with the same notebook, except with a dead screen. The screen would not and still wont turn on, but I hear everything going. This infuriated me. I am a student and I sacrificed four weeks without a computer, three of which had been since school started. I called Alienware Tech Support and they suggested that a cord must have slipped out of the motherboard. They proposed that I send in my computer again, setting me another two weeks, or in my case, another four. I asked for them to give me a refund for my computer and they told me to call customer service on monday. I am so ridiculously pissed off at Alienware. I will get that refund. But can anyone suggest how I go about this? I want to make it so they dont take advantage of the situation and let their way go through. Do you think their decisions were right in secretly cancelling my bluetooth and trying to pretend I wouldn't notice? What should I tell them in order for me to get my refund? I have a three year warranty.
