This call is like the others. 3473386188 for example. They are used to eat minutes on cell phones. All leave no message and all do not answer back when you pick up. These are ROBO CELL MINUTE EATERS. Question: Are they generated by the cell phone companies to make you buy more minutes? What can we do about this? I am going to investigate using http://www.donotcall.gov and see if the have a solution at the FTC and FCC.
