got a missed call from this numbershould I call them and leave them waiting?

The caller is Aussie Farmers Direct.  I phoned them back and asked why they are repeatedly calling without leaving a message and they explained that they were courtesy calls requesting feedback.

No idea who it is but will not answer anyway. They are wasting their time.
