Membership without credit card

I used to have a credit card and with it I paid for my Zwift membership last year. But now I don’t have it anymore. I do want to start using Zwift again.
Tried the option ‘change payment method’ and then it’s all about credit card again.
When I chose the option ‘DEBIT CARDS’ I was asked for a billing address. ?!?
PayPal suggests it is possible to pay with a bank card, but also there in the next window I was asked for credit card details. I do not have a PayPal account as I think I shouldn’t have to open an extern account just for using Zwift, right?
