If you pick up an unknown caller and there is no one answering, just keep hitting ##### and this is supposed to delete your number from their system. Don't know if it really works, but its worth a try. I get about 4-5 of these type calls daily even though I have registered with the do not call bureau.
I just received a call from this number- and it is on one of our lines at work- but not the main one- I answered it and I could hear something and they hung up
My neighbor has been getting numerous calls to his cell phone from this #. Now that I know it's a typical vacation scam I will block this caller from his cell.
