Update Netflix payment method is not working?

I had the problem that my Paypal account was accidentally not covered when Netflix wanted to withdraw the amount. Now the account has been blocked until the payment information has been updated. My question is, how can I tell you that you can debit it again?

You could write them an email.

Well, with Paypal it is not possible to update. With Netflix one should pay by credit card instead of Paypal, because one can update in the Netflix so.
