Horrible experience in trying to book viewings for different properties.

Horrible experience in trying to book viewings for different properties.Just to give you an example:In September they made us lose a property since we had an appointment booked but, on the day of the viewing, I had to call again since I hadn't received an address and they couldn't find our request.We had to book on the next available slot, but on the same day they cancelled because the property already had offers and we couldn't participate anymore. Ok, nothing to do, let's move on.In November, 2 months after, the same property comes back in the market.We call them straight away and we book an appointment for the next day.Calling them on the next day, again the booking was not saved, so I asked them to please send us an email confirming the booking.Guess what? Again the viewing, 2 days after, got cancelled.Similar to this happened with other properties, whoever is working in their offices is a real joke.Don't trust them and don't sell your houses through them.
