Now this is a scam of the first order. "Sign up for paper-free billing", and you're made to feel that it's somehow more environmental, more green and eco-conscious if you do. There's a few ways to go about it. You can sign up to have your bills mailed to your email inbox - OR - you can consent to direct debit from your bank account. I'd recommend against this, as when they cock-up, (and they will cock-up) the chances of you recovering your money are slender at best, and it'd be a full time job for a year or two doing so.
But you sign up for paper-free billing nonetheless, you can check and pay your bills online, and you're feeling pretty good about yourself. That's one less tree they'll have to murder, good company, good consumer. And when you check your mail while there's no sign of any bills, they've taken the liberty of sending you fliers that advertise all the other services they provide, internet, cable TV, the same fliers that used to be sent enclosed with your bill now get their very own envelope and are mailed post-haste. Just in case you didn't read the adverts on their website, just in case you wanted to be reminded. And - in case you bought that whole spiel about paper-free billing being more environmentally friendly - your S.O.L, it was just a ploy to get you to consent to direct debit. They didn't really give a damn about the trees, they just wanted access to your bank account.
