for about 3 or 4 months now my telephone rings from a company callled, Allied Interstate. They call early morning, afternoon, evening. They have called as early as 8:30am and as late as 9:30pm. They even call on weekends. They call any where from 3-5 times per day. With all of this calling, no one has ever left a message, so I have no idea what they are searching for. How can I block allied interstate from calling my telephone?
