Returnees, who arrived in Wau, Western Bahr El Ghazal state, demanded land for resettlement and compensation for personal belonging that went missing.
The returnees held a meeting at Wau on Monday and formed a committee to follow up their case with South Sudan Relieve and Rehabilitation Commission, Voice of Hope reported.
More than 90 families raised complain for not receiving their luggage dispatched from Khartoum since 2010.
Committee supervisor Benjamin Mayom Makui said 36 trailers carrying their personal belongings from Khartoum to South Sudan since 2010 disappeared under Relieve and Rehabilitation Commission custody.
He explained that the committee wanted to find out who was responsible for the loss of their belongings.
Mr Mayom revealed that they took notice that their luggage was disposed off in Khartoum after those in charge to bring it from Khartoum to South Sudan did not turn up.
Western Bahr El Ghazal State Government in March gave seven days for returnees settled in Hanker to evacuate.
Wau Hanker is located northwest of Wau Town and currently accommodates 87 families, repatriated from Sudan by rail and air since September 2011.
Most families have little to eat.
