I'm sorry for any confusion with this. When you set up your account you can chose monthly payment plan which gives you the option to pick your payment date. I'm sorry if that wasn't explained properly. The quickest way to get this resolved would be to contact our online billing chat team, though I can see you've tried that previously. If that doesn't work out then drop me over an email with the details and I'll look into it for you. You'll get the contact the moderators link in my profile.
