It is apparently legit but the character that left a voice-mail sounded a little too creepy for me so I checked it out. At first I thought it was an attempt at stealing information, but it was not.
Why do these idiots call people and not leave a message? I'll tell you why... Because they a slime ball scum bags that are trying to steal your hard earned money. Telemarketers are scum of the earth and are all not worthy of the oxygen that they steal from us!!!
