Ask Slashdot: What To Do About Repeated Internet Overbilling?

An anonymous reader writes "AT&T has been overbilling my account based on overcounting DSL internet usage (they charge in 50 gigabyte units after the first 150). I have been using a Buffalo NFinity Airstation as a managed switch to count all traffic. As you may know, this device runs firmware based on dd-wrt and has hidden telnet functionality, so I am able to load a script to count traffic directly onto the device. I have an auto-scraper that collects the data and saves it on my computer's hard disk every two minutes while the computer is running. While it is not running, the 2 minute counters accumulate in RAM on the device. Power problems are not normally an issue here; and even when they are I can tell it has happened. The upshot of all this is I can measure the exact amount of download bandwidth and a guaranteed overestimate of upload bandwidth in bytes reliably. I have tested this by transferring known amounts of data and can account for every byte counted, including ethernet frame headers. AT&T's billing reporting reports usage by day only, lags two days, and uses some time basis other than midnight. It is also reading in my testing a fairly consistent 14% higher whenever the basis doesn't disturb the test by using too much bandwidth too close to midnight.

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).

    I was going to say, ATM/PPPoE encapsulation is approximately 15% of total traffic. Bell Canada and all providers do that up here. I thought everyone knew this, or were able to google it especially if they are able to upload something like DDWRT to their router. Perhaps I had too much faith.

    This is exactly what's going on. The company I work for had this problem, at one of our warehouses (not AT&T, different provider, probably subletting from someone).

    The warehouse manager threatened his local rep with a law suit, they laughed at him. The company lawyer mentioned a class action law suit, they fixed our billing the same month.

    When we had to renew, the new contract spelled out that they will bill us for the 'resulting' traffic. It got signed without anyone from my department getting asked, but the funny thing is, months later, they are still billing us the old way i.e. without the overhead.

    As for the original poster - check your contract. If you have not agreed to pay for their internal overhead, you will get amazing results if you remind them that they are overcharging thousands of customers, and that they can be on the hook for millions, when a lawyer agrees to take the case for a percentage. If you have agreed to pay for the overhead... I doubt there is much you can do.

    By the way, I am an IT director ,not a lawyer, so don't go blindly follow my advice, either.

    My 2x4 lumber is actually 3.5" wide.

    Only if it has already been dried and dressed, it comes off the greenchain at the sawmill as 2X4 (to within 1/16th of an inch), as it dries the dimensions change, dressing the timber takes an 1/8th of an inch off each side. If a lumber yard attempted to sell you undressed timber as 2X4 that was actually 3.75 X 1.75 then the weights and measures people would definitely be interested. Here in Oz dressed timber is now advertised with real dimensions not it's undressed dimensions The practice goes way back to the days when most buildings used undressed timber for structural purposes. These days carpenters don't normally build frames on site, it's all prefab frames and roofs that just bolt together, for that technique to work it needs the more consistent dimensions of dressed timber.

    Nobody is scamming you out of useful timber, the industry terminology is well defined and is not hidden from the customer. The point of TFA is that comcast's network metering methods are hidden from customer scrutiny and nobody at weights and measures seems to give a damn.
