can I sue a company for not speaking to me on the behalf of my husband whom is deployed. In the state of Florida being his wife ?

It is not clear how you are harmed by the company's refusal to talk to you. As a general matter, in order to prevail in a lawsuit, you must suffer actual economic harm, not nominal or theoretical harm, and hurt feelings don't count. Since you don't provide any background on the inquiries you are making, it is also not clear why the company you are calling has any duty to speak with you at all. In the absence of some kind of legal duty, anyone is privileged to refuse to talk to anyone.
