From the format of the email address, we can deduce that:
Roger Greenberg: rgreenberg@minto.com
Michael Waters: mwaters@minto.com
Robert Pike: rpike@minto.com
Joel Bernardi: jbernardi@minto.com
I sent an email to those addresses to express my concern on this case, so far no bounce yet.

your english doesn't have to be 灵光, if you want to help, for lz and for future home buyer from those big builders, just send them an email to say that you're aware what was happening and want to see a good ending. let minto know how many people know this and they will take better attention on it, and solve it more properly.
