I once argued with AT&T when they raised my bill by issuing a fee (which violated the contract and meant I wasn't responsible for an ETF if I canceled). The CSR was convinced it was a tax, their manager also convinced it was a tax that they had nothing to do with. I kept kept saying over and over that private companies cannot levy a tax. I swear nobody understood this. This speaks to how successful these large companies have been at confusing everyone with their billing practices.
