I've been getting calls from the bell-solo scamsters for almost a year on a fairly regular basis. They have names like Robert or Kevin although their accents are urdu/punjabi, southasian ? frequently difficult to understand.If you try to "troll" these people or otherwise react emotionally they will likely put your name on their callback list. Unless you are a police or journalistic investigator and want to get some feedback from these parasites, just hangup.
