I was under a company visa then got a job as a private cook for a local family in January. Since then they did not make me new visa so I told them i wanted to quit but they denied me to leave. They went on to commit me as their domestic worker but I did not sign anything with the new sponsor. My visa is still reflecting under my old company but the new sponsor reported me for absconding and I do not understand how he managed to report me yet we did not enter any contract. When he noticed that i was asking for police assistance he chased me away from the house took away my passport, owes me 2 mnoths salary and denied me access to all my belongings. What should I do given these circumstances?
