Thanks a lot to all guys.
Per a post here, I have contacted Wood Laws, and sent the copies of my order and emails between me and BFL.
So far, they have not decided if to arise the cases to a class action, but they are collecting cases and evidences.
I guess they just want to see if this is worth to become a class action.
I am thinking to sue BFL at my local small claim court. It would not be too hard.
