It's a bit difficult to tell what happened - you're, of course, supposed to request FMLA leave in advance whenever possible, and if advance notice is not possible you are to notify your employer as quickly as reasonably possible following the qualifying incident. It sounds like your employer may be taking the position that you did not make a timely request for FMLA leave, and attempted to reinvent an unautorized absense as an FMLA leave after several days of absence.
Contrary to your impression, there are plenty of lawyers in Florida who handle employment termination and FMLA claims. If you believe you have a valid claim for wrongful termination, you should persist in your effort to have your case reviewed by a plaintiff-side employment lawyer in your state.
