They are *********** to the extreme of being ********

The lack of service and turnaround time is astounding. C fibre has been charging me for over a year for a 100mb fibre line and never upgraded me. Still on 20mb Kept on complaing and trying to reach someone. Finaly 3 months ago reached someone and since then just recieve a generic mail saying that the complaint is still with billing and sorry for the inconvenience. When stated after 3 months that id rather then cancel as im being charged for what i dont have. They want to charge even though im on a month to month They are *********** to the extreme of being ******** How can a billing rectify take a third of a year?
