Nearly new Laptop in for repair, comes back broken, no help from Lenovo.

Question

In February of this year I purchased a built to order Lenovo Thinkpad W510. It's a beautiful machine, and I was overwhelmingly satisfied for until about two weeks ago when the screen randomly went berserk, crazy flashing and horizontal lines all over the place. I called Lenovo support and was directed to take it to a local dealer, Express Computers. I did so the following Tuesday, as it was a long weekend, so even the day I dropped it off to be fixed I had already been without the use of my PC which is critical for my business.
Express Computers told me that it would be ready for pickup in three days, and that they would call me when they had diagnosed the problem. They never called, so I called them and they told me they were having difficulties because Lenovo was saying the screen must have been physically damaged. I treat this computer like a baby, it doesn't even have scratch on it let alone any damage to the screen.
I called Lenovo to inquire and they said they knew nothing about this, and I should have the repair shop call them. I did so, and the repair shop called me back and claimed that it was another department at Lenovo giving them trouble and but as a courtesy they would order the part and replace the screen anyway. At this point they explained that the reason they suspected physical damage was because some kind of metal bezel around the screen was all bent. I can only assume this was done during manufacturing, because it most certainly was not done by me.
The next day, which was Friday they called the say my computer was ready for pickup. I had now been without my computer for 6 days and unable to conduct any business activities (I am a web designer and photographer).
I took the laptop home, and it worked properly for about an hour before the screen went berserk again. I am now without my computer for a second weekend, and who knows how long I will be without it next week.
I took the laptop back to the repair shop today and they acted confused, insisted they replaced the screen and suggested I should be given a new PC by lenovo.
I was very happy with this computer, but unless Lenovo fixes this issue NOW, and apologizes to me for suggesting I damaged the computer myself, and makes it up to me somehow, I will NEVER purchase another Lenovo product, and do my best to ensure no one I know does either.

Thanks Jimbo.
I read your thread, although I don't think its gonna make a difference at this point. The laptop is in for the second time, and they told me it would be ready this morning and I just called and its still isn't done. Once the laptop is back in my hands I will be giving them a piece of my mind, and if its still broken this time I will be taking it elsewhere.
I hate Macs, but the one thing I envy about Mac users is how easy it is to get them serviced. No screwing around will third parties to screw everything up.
