I would like to know how to get this number to stop contacting me

Just another number to install on my phone's blocker list.

who is this

I'M getting the same call with no message on my answering machine and when i try to call the number back it rings busy, constantly.  Any one know who this is?

Direct Buy, if this is indeed where the number is originating as cougarjon stated, is a very pushy company. I tried to find out a bit about them and recieved numerous annoying calls, even when I told them I wasn't interested in signing on with them. They just didn't know how to take no for an answer.
