I have set my site as non auto renew
But the payment method said it still have active subscription. That make me cannot remove that payment method
Which should not. We should be allowed to completely remove payment method out of wix site. Please don’t do things like scammer site
Hey! Turning off auto renewal will end your plan when your subscription expires. Your plan is considered “active” up until then. Once the active subscription ends, you will then be able to remove a payment method. More information here. So yes, it is possible! 
thats rubbish,its about protecting your bank details from being abused,i.e Wix could have another hidden cost and bill it just like any other financial insititution. I am able to update payment method and remove the old card but then im still sitting with a card detail to be used. May as well be a scam!
