I attended the EDC in the suburbs of London and booked the tickets off a genuine website.
However, a friend of mine wasn’t this lucky.
She booked the ticket on what seemed to be the real website but realized the truth when she tried entering the venue.
To her horror, her barcode did not work and she got to know that her ticket was fake.
Always verify which websites do you use for booking tickets, especially third parties.
I strictly avoid any agents and go for the official website only.
