I got a call from this number this morning.  It's the same auto answering as the other telemarkerters about lowering my interest rate.  The best thing to do when you get these robocalls is to ignore them.  If you answer, they'll know you are there and they will continue to call.  Blocking these annoying numbers will only  generate different numbers from the same telemarketers.  Obviously, someone is having loads of fun doing this.  Don't give them the satisfaction by getting upset.  It's not worth it.
