I found this company on line while looking for a work at home job. I spoke with some one he said that they would send me catalogs and products to help get started for 500.00, then it was more money. I receved the catalog and the products, then nothing i couldn't get in touch with any one, so then i call to cancel, I was told that if i sent every thing back that i would get my money back, this was 2 months ago. I have been calling just to have them hang up on me.  My mother is ill, I help her with her bills and hospital bills I really need to get my money back. Please help me.
