c'mon Telus, you're smarter than that

So, I've been paying my bills online for years.  Telus still insist on sending me a monthly paper bill telling me not to pay it because the money will be electronically removed from my account.

The real kicker?  They send a self-addressed envelope for me to include my non-payment back to them.

I suppose there is a way to log into Telus' website and let them know the obvious, that I don't require a paper confirmation not to send them any money, but, c'mon Telus, you can do better than that.
