Dear Martin,
thank you for your review.
The tour you refer to did not include a tour guide, but only a transport service, your driver was in fact a taxi driver not a tour guide. The guided tours of the wineries are carried out by the staff of the wineries, as has happened with your tour. You can find confirmation in what the tour includes / does not include on the details of your booking (we are talking about a transport service and not a tour guide);
This tour is one of the most booked experiences among our proposals, we are deeply sorry and surprised to read this feedback.
