Subscription problem

Just renewed my ring doorbell 2 nd gen protection ( basic). Sent me email saying took a payment ( small deposit )- don’t understand why it’s not taken full payment ( says I need to authenticate/ authorise - how? )Says won’t take my payment until 26th of this month, until authorised/ authenticated? Meanwhile ring not working correctly I.e no detection no video saving etc? Why doesn’t it just take the payment now? I’ve no idea how to authorise/ authenticate- doesn’t explain. Please assist anyone who knows what I’m doing wrong- if anything I’m doing wrong???
