Billing Accounts

Customer service is non existent. First of all call center cuts off calls all of the time. No one is willing to help. Resorted to sending an email regarding the billing querying only to receive a standard reply. No one has bothered to contact me telephonically and account query status is listed as closed. Billed for data that I should never have been billed for as I was on a contract. In the email I asked someone to phone me and I am still waiting.
