Utility bills can be confusing. Unfortunately some unethical companies know that and use it to "cram" their customers with extra charges. Iowa Telecom spokesman Dan Eness says that can happen when a third party gets involved. Eness says "cramming" isn't something his company participates in, but their customers can be mislead by people who say they represent Iowa Telecom. Eness also says if something looks awry on your phone bill to contact your phone provider and have them provide a detailed explanation of charges.
