This is the problem with monopolies. No incentive to provide good service. IF you haven't already, start documenting your interactions with them. Take a note of each call, who you spoke with, and the specific numbers/things they said, if you feel that you are being defrauded. Have you attempted escalating this beyond the low-level employees? Imagine what a bureaucracy it is in a corporation like Comcast. Now do you imagine that the low-level "grunts" have much latitude for discretion in their scripts, or much knowledge/visibility into the other arms (support, technicians, install, netops ,etc)?
