They call at leaast 5 times a day on my cell. I answer and they hang up. I have not called back.

I just got a call from this number--was holding my phone when it rang so I answered it on the first ring.  Hung up--called back and got the "mailbox is full" message that others have reported.  Blocked number for the future.  Annoying!

how do I know that customized Website Pckg. is legit???????????????????????????????????????????

The reason that many of these scamers may hang up on you quickly, is that their power dialing software calls many numbers at the same time (multiple phone lines simultaneously). Their theory is that a majority of calls go unanswered or hung up on or go to voicemail anyway, so by calling many at once, as the first live person to answer, causes the rest of the dialed/ringing numbers to be released (you are hung up on). No worries for the scammer as your number will again be included in the next round of calls, and again and again. The computer is relentless, does not need vacation time, sick time, etc.

Sadly, in this day and age there is no respect for one's privacy. These [***] called my cell phone 5 times in a row. Something definitely needs to be done but, it will never happen because, I'd be willing to bet, the powers that be who are responsible for monitoring and controlling these types of situations are getting some kind of kickback!!!!!
