These people are a part of a large scale company of telemarkers who are trying to steal your hard-earned money. No matter what question they ask you such as, \"Hello. Is this (your name)?\" Never answer \"Yes\". They record every call they make and then, later, when you discover that they placed a charge against your credit card, they will produce the recording they made of you saying \"Yes\" and they will claim that you said \" Yes\" when they asked you if you wanted to buy something from them. Instead, answer your phone like this, \"What is your real name, what business do you represent, and what are you trying to sell me?\" If they refuse to answer, then hang up.
