Why doesn't Netflix work? Update payment method?

It is the case that we can no longer stream on our Netflix because we have blocked our account. (Because of private reasons).

In parallel to this blocked card we have another one so that we can withdraw money etc. Do everything.

Now we would like to update the payment method with this card. We tried this at least 10 times, but nothing works! What should we do?

I don't understand what you mean by "card" now. Another bank account? That should be added

You should contact Netflix customer service and ask this question there. They can actually see data there and also solve the situation, which of course I as an outsider can't do. Has the card itself or the Netflix account been blocked? Was this done in the browser or the app?

The Netflix account still exists. We still can't see anything. We have Netflix as an app on the TV

A card is not a bank account. A card can be blocked (e.g. After it has been stolen) but this has no effect on the bank account, it is still active. Also, you don't add a card, unless you mean a credit card, but the bank details. You have it without a card.

Express yourself better what you mean. Two bank accounts? Credit cards? In an emergency, you can also get prepaid cards from the nearest shop.

I just tried adding another credit card (as a backup) and that didn't work with the message 'There seems to be a problem with the payment method you would like to use.'
Maybe they're having problems right now. Wait until it resolves itself, buy a credit card, or call tomorrow.
