The mangmnt Comp. is returning my checks. About to get a LEAN due to it.

I have a small apt in Miami Springs, only property. I'm a single mother who is got a kid in College and my 85 y/o mother. I support them. Unfortunately, I had several arguments with the association because they are in violation of a whole bunch of regulations, they don't call to election and everything is just a rack. One of the directors had the nerve to take pictures of inside my apartment from a second floor balcony and I ended putting a restraining order. Now in retaliation they were first hiding the checks I'll drop at their door slot (of magmnt Company), who are very nasty with me and my old mother as well. They finally send me an attorney to collect the past payments, when I realized they weren't cashing the check but hiding them, I decided to talk to the president, who took my checks and told me he would take care of the attorney. He didn't. A year later my case is still with the attorney, and the management comapny is still rejecting my checks and they are sent back now.
