We could not do the excursion to the Wanda Mines (Misiones, Argentina).
Because we booked an excursion for the morning at 8:30, and the operator NORDIC informed us after 5 PM the day before (less than 24 hours to cancel), it seemed disrespectful to us, it ruined a day of vacation, and we are very angry. We requested a refund but have not yet received a response.
