I have just purchased a service, why is it asking for my card details when I book a session
This could be that the service you have bought is not for use on the particular session you wish to book.
Or this might be an issue on your professional's side 😱 They might not have their services turned on in the calendar for the particular session.
Please let them know you are unable to book and ask them if your purchased service is supposed to be turned on in the calendar or if it is available for use 💪
They should be able to sort this issue for you or give you a suitable answer.
