Rotten service & support

On 2/9 Dell sent a technician to my house to replace the on/off switch in my Studio XPS7100. I could tell he was not very knowledgeable trying to take the side panel off. I had to remind him to unplug it. In replacing the switch he broke a wire on the new one. He had to reinstall the old switch. He has all kinds of trouble plugging the switch in. After he was done he started up the computer and it was dead no OS. He ran diagnostics it said bad hard drive. He put on his coat and left. I got back in contact with dell support about my problem. They said they would send me a new hard drive. I asked them to overnight it they sent it two day express with week day delivery only. So I got my new hard drive on monday the 15th. I told them I would put it in myself. After three days of installing my mirror image I finally got my computer up and running on the 18th.I asked support because of time lost and all the problems how about sending me a 2TB instead of the 1TB they said no. How about extending my warranty they said no. After all of this I am left with loss of computer for 9 days and I get nothing. I think later this year its is time for a "MAC"
