My new computer and some really bad customer service

So here's my story about buying a new computer and some of the worst customer service I've ever had.
I went to the computer store to get a new mother board for my computer. A friend of mine did some research and told me what I could get. Basically I was just looking for an inexpensive way to prolong my computer's life for a while. I went to the store knowing exactly what I wanted. The person helping my asked if I had my computer in my car and wanted to look at it. I did have it and I brought it in. He had a look and said that I should do more of an upgrade and my computer would run way better. The initial board I was going to get was going to cost me about $150. The upgrade would cost around $320. After him selling me like crazy on it (when he wasn't trying to get me to finance a whole new computer) and me humming and hawing about it, I went with the upgrade. Cool, I was happy and excited to get it home and fire it up. The only problem is that I couldn't hook all my drives and stuff up to it, because it didn't have all the connections. I took it back even though the bill said no refunds under any circumstances (I had to sign the bill), because he looked at my computer and sold me something that I was under the impression would run my stuff. It turns out they meant no refunds even if the sales guy suckers you into to buying something you can't use.

I went back with my box of stuff and low and behold the same person who sold me the computer parts was at the front desk. I explained to him that the board he sold me wouldn't work with all my stuff. He said that they don't sell boards with all the stuff I needed anymore (my last computer was only 5 years old....go figure). I explained that after he looked at my computer and sold me something that he said would work, that it actually would. I told him that I would like my money back and that I would like to have a look at what kind of new computers they could set me up with. Well he abruptly told me that I couldn't get my money back and there was nothing that he could do. I asked his managers name and he told me that I didn't need to talk to a manager and that he was more than capable of handling this situation. I was floored that he would have the nerve to say that. I insisted that he get a manager. He left and came back about 5 minutes later and said the manager was too busy to talk to me. I couldn't believe what I was hearing. He suggested that I buy new drives that would work on the new board. for $25 a piece (I needed 2). I told him that I didn't want to buy anything else for the thing that he said would work for me. I then accused me of nickle and diming him. WOW! now I was pissed! I explained that I CAME IN TRYING TO BUY SOMETHING FOR $150 AND THAT HE AGGRESSIVELY SOLD ME SOMETHING "BETTER" THAT WOULD WORK WITH MY COMPUTER. THE VERY COMPUTER THAT HE OPENED UP TO HAVE A LOOK AT. I CONTINUED TO REMIND HIM THAT I ALREADY SPENT $120 MORE THAN WHAT I ORIGINALLY INTENDED AND THAT i DIDN'T WANT TO SPEND ANY MORE ON UPGRADING THE UPGRADE THAT HE SOLD ME I made him go get a manager 2 more times and both times I got no manager. Unreal!
Once he offered me store credit (he said that that never happens). At that point I didn't even want to shop there. I told him I would have a look at some computers in the store once the money was in my pocket because after the service I received, I didn't want to be obligated to buy from them. He pointed to a customer service award on the wall and said they had great service. Finally I got fed up (I'm not gonna lie I had to get out of there because I wanted to punch the guy right between the peepers). I ended up buying one drive and he bought one. He then asked if we were still upset. I said of course we are. We (my girlfriend was with me) just got the crappiest customer service we've ever had. Do you know what he said to me? He said that I would be back next week to shake his hand. Do you see why I wanted to pop him one....lol. I told him I would never be back until his manager decided that he could make time for a customer who is having a problem and we walked out. I then went to another store to buy parts to build a brand new computer around the stuff that the "jerk" sold me. We dropped another $400 in that store because we where very happy with the way they treated us. The other store lost out. We've spend around $3000 in the last 5 years (which I also explaind to the "jerk clerk") and now they will never see another dime from us. ...... to be continued............next I'll tell you what the manager said when I phoned him.
