However, the following day, TS Entertainment issued a press release refuting the claims made, stating that there were "neither such maltreatment to the artists nor unfair clauses in the contract.” Their statements were challenged when B.A.P released another statement claiming lack of accountability and saying that they were considering filing for defamation of character.
