Bought tickets of colloseum which said skip the line. It was self guided tour. On the day struggled to find them and when I eventually did she didn't know my name and then called people and realised I should be on the list. Sent me entry passes for completely random people. I asked as it said to bring ID and they check. She dismissed it saying it'll be fine and if they stop at security checkpoint then come back. Not only was this against GDPR and data protection, it was dangerous and could have gotten me into trouble. Had to still stand in the line for 45min before I got in panicking throughout as ticket wasn't in our name. I wonder if they gave tickets with our names to other people which would be another data breach. On the way out I realised the tickets cost €16 for which I had paid them €42.90 per person
