HOA bullying me in FL (Tower management group)

[Apryl Hudson]

I live in Florida. My HOA management company (tower management, aka: space coast management, lighthouse properties international llc, lighthouse properties management south florida, lighthouse properties management group,) has been a nightmare, since they were hired in 09. I recently filed a BBB complaint against their constant harassment. Of course, they lied in their responses, but since I only would communicate through email, I had proof of their lies. I have had problems with them, 'misplacing,' my payments, then charging me late fees. One check they clearly cashed, (I got the cleared check from the bank,) yet they wouldn't apply the payment until I provided proof they cashed my check.
They recently insisted on communication only through certified mail, or get the lawyers involved. (They claim this is statute, to which I cannot find.) This, 8 months after I sent them a payment plan, (and an invoice for my time, long story,) certified mail yet, they claim I never sent them anything. Then, in one of their BBB responses, they scanned the letter I sent them into the site!
Now, they are not cashing my check...again. I am being harassed by this company! How is this legal? How do I get them to cash my check and do their job? I would cc the BOD through email, so they could witness the ridiculousness of this guy. He told the BOD to put my email in spam..and they did! One of my neighbors told me they laugh at me at the meetings. We are currently looking for another house, but it takes time. What can I do? How can I make them cash my checks? How do I stop them from getting lawyers involved for something so stupid? (Wasting more of our money.) What are my legal rights? What is this statute that states that communication is only through certified mail, or attorneys? Thanks
