What should I do? Should I see a lawyer or not?

I worked at a hotel that let me live there at the same time I've lived there for three months and I had to pay most the time my whole pay check which I was being cheated on. Worked 45 hours a week only get paid 15 to 20 hours. I ran that hotel desk and did house keeping and also do laundry but randomly they fired me and kick me out with no reason and no explanation. I have a document stating they would let me live there 12 months but only let me 3 months. I have four kids and now we are very much struggling cause the situation they put us in. Now they kicked me off the property and say I owe them money. But I don't and did nothing wrong to get fired or kicked off property what should I do this happened in davenport florida
