Patreon money help

hey guys so I payed $18AUD for a month for not lovelines patreon I am tight for money so had to cancel it to make sure I was only charged for the month but I already can’t watch the videos, I only payed a couple days ago. I’m confused because I’ve done this before you still get the month that you payed for and tells you when in expires anyone have any idea on why or what to do?
