Not only is this a disreputable marketing company, but if you call them back you will be assessed a fee on your phone bill. I used Google Voice to call all suspicious phone numbers, and when I tried to call these guys Google Voice said that, "I do not have enough credit to call this number."

I keep a very small amount of credit with Google Voice for this exact reason. Now I will add this number to Google's spam list and they won't be able to call me through Google Voice ever again. I forward my home phone through Google Voice so the spam function can screen all those calls and it works perfectly. No spammer can call me more than once when I use this procedure.

I have been called on my cell by this number about once a month for the last four months.  I do not answer and there is no voice mail message. Irritating.
