Metrofibre billing ****

MetroFibre service is the worst. I have been on a month to month service with them and I thought everything was fine until the last 5 months. After paying every month for the service they decided to change the invoice date did not communicate anything and then they are now claiming I am a month behind and threatening they will suspend my account. When I call them to understand what is going on one of their agents decides to drop the phone. They are ****** and should not be used for their service.
