I found this helpful discussion, but it's 14 years old. Thus, I thought I'd post my question here. Do any of you enlightened Slashdotters have insights to this problem, or know of any products that will help me achieve my goals?
AT&T has already refused to attempt to fix the billing meter, and asserts they have tested it and found it correct. Yet they refuse to provide a realtime readout of the counter that would make independent testing trivial. I've been through the agencies (CPUC, FCC, and Weights & Measures) and can't find one that is interested, AT&T will not provide any means for reasonable independent testing of the meter. It is my understanding that if there is a meter and its calibration cannot be checked, there is a violation of the law, yet I can't find an agency that can even accept such a claim (I'm not getting "your claim is meritless", but "we don't handle that"). If indeed they are not overbilling, my claim of no way to verify the meter still stands. My options are running thin here. So that my account can be identified by someone who recognizes the case: 7a6c74964fafd56c61e06abf6c820845cbcd4fc0 (bit commitment).
