I keep getting calls from this numberto sign up for credit card terminal.  The caller I.D. says the company's name is Maximum Research but the person talking introduces themselves as calling from BPS.  I asked them to stop calling because I'm on the national Do not call list, but the excuse I get is they look up numbers from yahoo yellow pages.  I also asked them to put me on their internal do not call list but I was told they don't have such a thing.  They keep calling every day eventhough I asked them to stop calling.  I have already submitted a complaint to FTC.  Anyone else has the same problem
