Payment Methods

Zoom sent a notification that the validity period of the credit card used to pay for services is ending and that we will lose access to PREVIOUSLY PAID services.
Do I understand correctly that we will not be able to use the services that we have paid for?
What does it mean?
Or will we still be able to continue using the paid subscription until the end of its validity period?
Should we be worried?
Thank you in advance for your help.
