No bills

I stopped receiving my monthly itemised bills in October 2014. I have logged 2 separate complaints in the last two months, and not a thing has been done about it. I need my bills for tax rebates, AND it is a service I pay for. Nobody can answer why I stopped receiving the bills, nobody can answer why nobody followed up with me if there was an issue as to where to send them. I am appalled at the service. I have had this contract for almost 9 years now but I will consider other service providers after this exeprience.
