Has anyone else run into this with Verizon and is it possible to hope that I could pay a prorated bill like every other utility in the world? In any case, it further reinforces what a ripoff Verizon is and how I made a good choice to terminate their service.
This is yet another pitfall with postpaid accounting with mobile service providers. Verizon bills for the entire month and doesn't prorate the base calling plan, only the add-ons. The key when leaving Verizon (especially if you're waiting out a contract) is to time your number porting and departure between your contract end date and the last day of the billing cycle for that month to minimize financial damage. There's not much to be done as this is a contractual thing you agreed to. Feel free to file complaints with regulators in your state, the FTC, etc., but don't expect your money back.
Unfortunately, this information at this point doesn't do much for you, but it does serve as a useful but cautionary bit of info for anyone else desiring to leave Verizon, AT&T or Sprint for cheaper pastures.
