Sorry to segue slightly but on this topic of personal information I was actually cancelling my Netflix membership and they don't even let you remove your card details.
Upon speaking to the customer rep they said that I'd have to contact their privacy department (or some faff like that) but if I did have my card removed I wouldn't be able to access the rest of my subscription that I had already paid for, I guess what I'm trying to say is - it could be worse
In that case you contact your bank, cancel the continuous authority and then order a new bank card whilst battling with Netflix because if you ever change your card, they'll get the new number without you ever telling them. I discovered this when my bank card expired and I logged in to update my card details and discovered they already had them.
That's one of the reasons I've left my Barclays account open, and am now using it purely as a Netflix payment account, (I transfer money to it to pay Netflix a few days before it's due), that's the only payment into or out of that account. I definitely wasn't gonna give them my new account details.
But definitely pursue the removal once your subscription is over.
Thanks very much for that information, I didn't know the problem ran that deeply.
I'll definitely speak to my bank to stop the continuous authority. The funny thing is that I really did quite like Netflix (before this anyways), but the behaviour they have regarding card details is so off.
I can somewhat understand if I were just trialing the account and they wanted to try and get me to sign up for the subscription, but I'm a long standing customer that has cancelled the membership already, it's just awkward, especially threatening to stop me from access that I've already paid for, just for wanting to remove the card details.
Makes me hate them a bit and I was going to rejoin again when I had the ability to but I don't think I will anymore.
