Excellent customer service.
I booked tickets to see the Sagrada Familia but was refused entry. To cut a long story short the tickets were accidentally sent to the wrong email address so I didn't get them and had to buy new ones on the day. A quick WhatsApp message with customer services and I was given a full refund and an apology for the human error so I'm happy to give a full 5 star review. I would not hesitate to use again.
