Yeah, it's not all peachy there either. I made the same assumption till I went to the bank to "block" a service-provider that kept insisting on billing me. They "blocked" the service-provider from charging me for 3 months, then they were apparently obligated to let it through because they could only do it for 3 months. At which point, the service-provider just back-charged me for those three months and continued anyways.
