Hello Adriarob,
Are you part of a Family Sharing? Below is the article about Family Sharing but from what you are describing it sounds like you are part of a Family Share plan.
What is Family Sharing?
If the organizer lost his phone, did the organizer cancel the payment method that was on the account for Family Sharing? If so, they will need to update that payment method or disband the Family Sharing for now and each individual can use their own payment method.
If you need to change or update your Apple ID payment method
We also want to provide the article for cancelling Family Sharing if that is the route you's chose to take.
