[quote=CBad]I’m not that surprised by the people. I have run into similar math skills at stores in the past. But I still don’t understand why the software is wrong and billing him incorrectly. Unless one of these humans put the wrong billing rate on his account in the first place.[/quote]

The software billed him correctly; what happened is that when he called and inquired as to the billing rate before a trip to Canada they quoted him the wrong number.
