Wtf is happening in the US? Here I get an advertised monthly price for my subscription, I set up a direct deposit for that exact amount, when I buy it, then forget about it.
Maybe there is a commencement fee one time for the equipment they give me or work they do, but that's all.
How is it legal to advertise and agree on a price, then send random bills?
The companies make the rules since bribery is legal (see lobbying). They set whatever price they want, then use the money to buy the politicians that continue to create stronger pro-corporation laws continuing the lack of choice and change.
Yeah mine is fine in Canada the price is the price per month till a renewal (biyearly). And if you call them they can breakdown bundled price into what each service costs (for business tax expenses)
