This number is Charter Com in St Louis. The cable company uses this number to harass people into buying new things such as phone or internet. Contact the better business bureau, and file a complaint. They have helped me get them to stop calling 5 times daily, with threat of a harassment lawsuit.
Charter Communications trying to get you to bundle everything up. This is the fourth time they have called me in 2 days despite me telling them to put me on the do not call list...
