Problem with brand new MacBook Pro

Hi, I just bought a new Macbook Pro.. so today when I opened the lid, the screen started flickering slowly, then when I clicked the mouse it would go crazy.

I have never dropped it, or anything like that, it is a few days old.

I had to force turn it off by holding power off button, after the restart, the problem is gone.. for now..

Oh and one last thing, there is a little light leak coming from the top of the display, it is very hard to see, and yet I saw it when I'm using the Mac in total darkness.

I have included a video of the flickering, and a photo of the leak.

I bought insurance at firm called Securator, but.. should I return it to the electronic store I bought it at instead? or what should I do?

- Thanks
