Ozrwys send email reminders to renew your subscription.
They specifically include a link direct to their webpage for you to renew, asking that you renew directly rather than through a third party site (who takes a commission, and Ozrwys get less money).
But their website doesn't allow this, if you want to go to a lower subscription.
Not very smart on their part.
I wont comment on your remark. You're really not worth it.
