Urgent: Clothes Lost, Pregnant Teen Needs Help

My daughter's upstairs neighbors moved out of their apartment and hired a cleaning company. The cleaners in a rush took all my daughter's clothes she was washing and drying out of the laundry room and threw them away. It was all her maturity clothes and school clothes. They left her with little to nothing to wear. She has to wear all black to school. We can not afford to replace all her clothes. She is 19 and pregnant with her first baby. I contacted the rental management. They say there is nothing they can do. The contact information for upstairs former tenants is not public information. The cleaners said he put them in a dumpster. I begged him to let us know where so we could go look for her clothes but he would not tell me. He said he would go look later in the afternoon. Once I finally convinced him to please go look for us he said the dumpster was empty. Any help would be appreciated.
