A recording of "Pastor Fred" pitching a religious book and a book signing event. If you pick up this call your line will be captured by it until the recording finishes playing - about 90 seconds...!
The message is from Pastor Fred, but they are not trying to "capture" your number. You may have an old number of a member or supporter or perhaps they misskeyed when entering the data. Just call them and they will remove your number. It's not difficult. No one is trying to "capture" your number.
