Called three times in succession. After a few seconds of "hello? hello?" the guy comes on and says he's from Pakistan and asks if I want to be his friend. I tell him this is a business and to please stop calling. He calls again and a third time, asking what business it is. I tell him and ask if he has any business with us. He says yes, so I ask what it is. He doesn't speak. So I tell him to please stop calling and he agrees. Then I make him promise to stop calling. It's been a few minutes and I haven't heard another peep out of him. I hope it works.
