Link not working

when I have people clicking on the link this is what they get:

We’re really sorry - this booking profile is not available right now.
Please contact the calendar owner.

Please help what do I need to do?

Hi Milena, looks like you have paid features enabled on a free account. If you open your booking page settings you’ll see the sections highlighted in yellow to resolve and get your page back online.

Where do I do that as I cant’ find how to I was on the paid as I signed up for the free one?
