and it was warped like it was bent concave... not supposed to be like that is it?

It should not be like that. If you buy it from a shop or somewhere else it will be level.

I suggest contacting the person you bought it from.

If not, then it will probly just go back to a flat shape then you screw it in. Just DONT GO TOO FAST, go slow and screw evenly on each hole.

Im not saying your a loser.
