Do not use Delfont Mackintosh to purchase theatre tickets, customer service is appalling. I purchased tickets to see the musical Oliver in November 2025 and booked specific seats for a reason. On arrival yesterday 30th June 2026, we found our seats had been changed without prior discussion or our permission. The theatre box office dressed the seat change up as an "upgrade" which I have never heard of before! In reality our seats were already occupied and we had no choice but to take the new seats offered. The view was terrible for various reasons and our evening ruined. I contacted Delfont Mackintosh customer services by email the following day as the Gielgud Theatre does not have it's own customer service department and their response has been a disgrace. They already had our money (£340) and could not have cared less, using every excuse they could find. I would definitely recommend to use an alternative ticket provider so you are not disappointed and actually get the seats you book!
