Booked a tour of Teatro Colon in Buenos Aires. when we turned up the theatre guide said the ticket was not valid & I had to pay for new 2 tickets directly at the theatre ticket office. They cost less than half the price Get your guide had charged me. When I contacted them they said as my tickets hadnt been scanned they could not refund me. I screen shot the tickets & tod them them that hadnt been scanned as were apparently not valid & also sent them a photo of the actual tickets I had to buy for the same tour & never heard back from them. They are a complete scam & manage to get themselves to come up first when you search for a tour you want rather than being able to find the actual operator. AVOID AT ALL COSTS
