I booked tickets for a tour of Teatro Colon in Buenos Aires. I followed the instructions, recieved tickets with a QR Code as instructed. When we turned up the ticket collector said I had to go to the theatre ticket office & get them converted. They fortunately let me skip the queue but the ticket office told me they did not recognise the tickets & I woukd have to purchase new ones directly from the theatre. They were considerably cheaper & when I contacted GetYourGuide to tell them & request a refund they said they couldn't do that as they could see that the tickets they sent me had not been scanned. I explained that they weren't scanned as were apparently not valid & I sent photo of the actual tickets I had to purchase for the same tour. Have heard absolutely nothing for 5 days. Would have to say do not use this company as seems like a complete scam.
