Big Bang fans in Indonesia turned from "Fantastic Baby" to "Blue" after the group's concert failed to live up to the hype, allegedly because of the local promoter's poor planning and production.

After Big Bang finished their MADE World Tour concert in the Indonesian capital of Jakarta over the weekend, disappointed fans took to the forums to complain about their concert experience.

"Please read this and take it as a lesson. From a disappointed VIP," started a letter from the disappointed Twitter fan Lily Quinn.

Lily Quinn's letter, which was addressed to YG Entertainment, outlined 13 major complaints which mainly focused on the "very incompetent and unprofessional" way that the local Indonesian promoter conducted the concert.

The fan letter described a "queue chaos" during the event. "There was no one directing and controlling the queues," which then led to confusion and frustration as fans had to bear with pushing and screaming at the lines, and attendees allegedly entering sections they weren't supposed to.

There was also a big disappointment on the concert's production values. "The stage was plain and small. Period. It was like a stage from a school festival, not K-Pop royalty Big Bang concert."

Worse, the fan letter claimed that the concert had awful sound and visual systems.

"The sound was so terrible I thought it wasn't a Big Bang concert. The speaker didn't give me goosebumps, the mic was too soft I can barely hear BIGBANG, the right screen was off for more than half the concert," the frustrated VIP fan narrated, listing many other problems.

Below is the complete fan letter:
