The culprit for these numbers is a company by the name of bizrate. They do online marketing for companies that offer free trials for products. If you sign up for one such as becoming a tester for a product like ipad once they get your information which they can by a simple click onto the site, they download your information to every one of their associated clients. I have ended several of these types of harrassment phone calls by asking the person on the other end to give me his/her name. Then I ask them to spell it for me. Then I also ask for their last name. Nine times out of ten they give it to me especially if their name is common. Then I just tell thank them for the information and inform them that I will be turning their name into the U.S. Attorney General's office for harrassment. Most of them tell me they just work there. I tell them it makes them an accomplice and remind them that they are the ones doing the harrassing.
I have received phone calls from this number several times. They don't leave a message. I refuse to answer it. I would like to stop them from calling but don't know how.
