Seen some one said they paid £25 for parking
Yasin, 20, told BBC Newsbeat he paid £25 for parking and arrived at the venue to be handed one of the pieces of paper.
He said: "I'm thinking is this real? Why isn't it online? It was very unprofessional, I couldn't believe it almost, like is this the way we're finding out that it's been cancelled?"
Yasin said he had been looking forward to attending the show and had been listening to the rapper's music "on repeat" for two weeks.
"It makes me question future events, if they're going to be planned properly or if it's going to be organised enough", he added.
