Start an internet contract brokerage where the "broker" handles all the contract negotiations, including the speed and price for all their members, contests incorrect billings, and doesn't let their promotional price lapse.  The representative will get everyone's billing contract onto the same date and then negotiate when the contract comes up for renewal.  The leverage will let them get better deals, and they can threaten to leave the company.  The salesperson will be likely to cave under the pressure of losing 100 accounts at one time.

The brokerage would also recommend dropping unnecessary services or explaining how to get those services cheaper and easier from third party providers, such as leaving aol, using a home line via google voice, home security via blink, and buy your own modem off amazon.  The brokerage could take the slower modems back and sell them to slow package customers if the high end customers buy a really fast modem for fast internet packages.

This would reduce a lot of scams that prey on the elderly.  It would be a boon for municipal fiber companies that don't have the marketing dollars of the big companies that offer an inferior product.
