It is Centenial Windows. I have told them 4 times not to call me, that I do not own this house. They never remove you from their call list. They are supposed to, otherwise they will get charged. Well, I want to know how I can get them charged for calling me day after day! I work at home and I need quiet because I record.....it does not help when I get interrupted by the phone ringing!!! PLEASE STOP. I do not know how to report them, so if you do, please tell us.
