Wrong Invoicing and payments

Every month my invoice has extra things added to it when I should only be paying for a phone line. <br> <br> I do not have my ISP through you and I do not even have telephone to make calls from!<br> <br> I need someone to contact me ASAP so that this can be rectified. Every request I send through NOTHING gets done about it.<br> <br> You cannot continue to rob people from their money and then not even give them the service they are paying for or answer your phones. It takes over and hour to get hold of you then when I finally get through to someone, the call all of a sudden gets dropped and i get disconnected.<br> <br> Please contact me ASAP.
