What should I do if my attorney won't contact me?

I hired an attorney not local from me, basically because he was cheaper. I paid him $850.00. He filed the divorce paperwork, which he gave me a copy of. I waited the 90 day waiting period, which was up in October 2014. I've spoken to his assistant who said the final papers were on his desk to be reviewed. A week later, I called and spoke to him, who said the documents were emailed to me, in November 2014, of which I stated no I've never received them. He was supposed to send them again. I've been calling and calling him, he either never returns my calls, or I get a machine. I started with him in August of 2014. I need some advise on what to do about this shady lawyer? I paid him with a credit card so I have proof of the money I've given him.
