Things don't end well when you anger a K-Pop fandom, especially for a much loved, big group like EXO, and boy, were EXO-L's angry about the group's recent concert in Shanghai. 

EXO-L's indignation wasn't directed at EXO, but rather, the organizer of the group's 'K-Friends' concert which was supposed to be held from 7:30 p.m. to 10:30 p.m. (local time) on March 27. 

The organizer had promised ten songs, a solid 3-hour concert, a variety of different performances, and most importantly, the presence of Lay.

Due to the high demand for these tickets, prices were said to have gone to an upwards of 10,000 yuan (~$1,527 USD) for front seats, with regular tickets going for anywhere between 4,000~6,000 yuan (~$615-922 USD).

With all these promises, fans were undeniably excited to watch all nine members of EXO perform for three hours. Needless to say, EXO-L's couldn't find the words to describe their disappointment when the concert ended abruptly before nine o'clock even struck, only five songs were performed, and Lay was nowhere to be seen due to being busy with filming for a movie. 

When angry fans protested about the false promises and demanded a refund, the organizer of the show pushed the blame to a third party, namely a Chinese ad agency for false advertising. 

According to various sources, the organizer claimed that "there was a Korean company as well as another Chinese ad agency involved, and the Chinese company was the one who breached the contract." The organized further claimed that they did not "know the details of the contract" and that reps from the Chinese company failed to show, which somehow disabled them from contacting the Korean company. 

The host assured fans that they will be releasing information about potential refunds soon.
