I believe I saw this movie about 5 years ago (2010), in English, not sure if it was on TV or not but I’m certain it wasn’t a show. It was in color.

As for the plot, the beginning scene involved the character who I believe is unemployed. He sees a commercial on TV I think for a “get rich quick” method or some sort of advertisement and he calls the number (and maybe gets his friends together.) Ultimately, they end up fixing up a mall or it at the very least takes place at an abandoned mall.  Sorry for being so vague, in fact I don’t even remember if the genre was comedy or horror, or possible a horror comedy.  Thank you
