Glitchy AF

So I finally gave in to the constant advertising and encouragement and decided to sign up for my 14 day trial. I signup, aaaaand even though i used the exact same card details as Netflix and all my other debits, they cant confirm my card. I reload the page, it takes me to signup. Then it says i already signed up, but every-time i try click sign-in, it just reloads the sign-up page, over and over again. I even tried clicking the link in my confirmation emails, but it only loads the page briefly and then the signup page, again. It was a colossal waste of time and i'm still unable to log in or use the service. Back to Netflix it is! Plus I'm going to tell all my friends that it isn't worth it.
