stop calling me

Have received 6 or 7 calls in the last three days from 206-319-9740. No name with the number. I do not answer the call, if I do not know the number.  I am on the National Do Not Call list, so why doesn't these people have to follow that list. They never leave a message.

Same here. They just keep calling me everyday. Same number 206-319-9740

same here they've been calling me all day !!!

Just called me,left no message. I would like to know who this is.
