not accepting my debit card details .( start free 7 day trial for mediation)

I would like to upgrade my membership after 7 day free trial but when entering my debit card details, a message comes up that it was outside perimeters.

I am attending the group healing taking place in London and received an email today (20/3/23) stating that in preparation for the event, it is recommended that I listened to a list of meditations but when clicking on the join here , the page that I am being re-ditected to, is unloadable.
