Lack of honesty and credibility in dealing

The nursery owner lacks honesty and credibility. An order for 100 olive trees was booked with confirmation on 03/11/2026, with the agreement to receive them after 3 days. When we called to inquire, we were met with poor treatment, and this was after 6 days. There is a loss of honesty and credibility in the dealings. How can he make me trust the product itself....
