Last night (1/20/09) I receive a call at home from this number and the person on the other side I can not even understand but two words out of the conversation.  They said something about I should interest in doing something, like I requested the information.  I told the person I don't really understand what you are saying but I am NOT interested and please don't call.  Today I received the same call but this time they hang up. I called back and it just has a fast busy signal.
