Fraud ALERT ⚠️ this fraudulent app owner charged me 3000 korean won for telling me there are more than 30000 korean won to be returned to your bank account. when I paid 3000 korean won, I got a message from this app telling me there is no money for you to be returned to your bank account.

안녕하세요. 삼쩜삼입니다. 최근 환급액이 있는 일부 고객님을 대상으로, 환급액이 없는 것으로 알림톡이 오발송되는 경우가 있었습니다. 이후 정정 안내를 드렸으며, 이용에 혼란을 끼쳐드려 죄송합니다. 본 리뷰는 글자수 제한, 고객님의 삼쩜삼 이용내역에 대한 확인이 어려워 자세한 상담이 불가한 점 양해 부탁드립니다. 서비스 이용과 관련한 상담은 앱 내 [전체>고객센터] 혹은 카카오톡 플러스친구 [삼쩜삼 고객센터]로 말씀 남겨주시면 1:1 안내 도와드리겠습니다.
