I do not normally answer unknown, not provided, private or any other number that hides identity. I respect the caller's wishes to be anonymous by not picking up to find out who it is. My answering message indicates this.
Received a call from this scammer this morning (06/24/16). I never answer such calls. As it regards this particular call, they left a message, claiming that I had requested information about a back brace. Well, needless to say, that was a complete lie. Then, as these scammers sometimes do, they asked for the recipient of the call to press 1 to speak to representative, or 2 to request no call backs. One should NEVER press and number, PERIOD! This only confirms that it is a working number. Remember, all they want is your credit card information so that they can steal from you. They should all be in prison.
