That's one option that always works, and people don't seem to get that. While it's scummy that you have to do it that way (that's obviously bollocks), this would also be the way to tell them to stop charging you if their customer support won't pick up, their email server rejects yours as spam, the web form is broken, that sort of shit (people elsewhere in the thread mention a million-and-one instances of this, not realizing that there is another way). Send them a letter and be done with it.
