Your saved cards are resolved for your signed-in payment identity. Being a member of the same team does not expose another person's saved-card list. The team's automatic payment agreement and your personally saved cards are different things.
Confirm the account and payment method selected in Buy credits. Use another card for your manual purchase if the intended method is not in your list. To change automatic charges, use the agreement's own controls. If your own expected card is missing, ask support using only the brand, last four digits, and relevant purchase reference.
