We noticed a LDC monthly fee from OAN Services of 8.23 per mo. since Frontier bought out Verizon. We called and disputed these charges as we already had a LDC carrier outside of Verizon for years. These disputed charges totaled $49.38 which included Frontiers late fee . I have emailed Frontier four (4) times and no response. I still have not heard from either companies or received a credit from either of them since 10/27/2010. This slamming charge plus late fees now total $62.64! Still paying my normal bill of $74.42 a month . Still waiting for a email, a phone call and above all a credit for disputed charges.
