Human Rights violations

Immigration officers in Singapore are really ###. We have come to Singapore for vacation and denied our entry for no reason at all. Maybe others would come to work there but that doesn't mean all? Why do innocent people that only want to visit gets treated like that?? Just cause we are Filipinos? We have everything they ask return ticket, hotel booking everything they ask us. They even take our phone and trespass our privacy. They put us in a room locked us there for 24 hours for no reason. We were like criminals. We got nothing to do we were guarded everywhere we go and limit our use of phone. We just wanted to visit that's all. They are racist they can just treat asians mostly (Filipinos, Thai, Vietnamese, Taiwanese ) treat them as criminals for entering the country. They don't even hesitate and don't even think about money we spent on our tickets and hotel bookings. They can't even prove anything. We were guarded like we murdered someone. That's was first time in my life being treated like that. They sent us home on same airline next day and left us with trauma. Only good thing happened is when I met a good friend from Taiwan at immigration prison at the Changi Airport. Never going to Singapore again..
