If I gave the lawyer retainage am I entitled to any monies back if it wasn''t all used up?

I had hired a lawyer to stop the divorce process for me and then I decided to continue with the divorce. The lawyer took all retainage of $5000.00. I saw the lawyer on Thursday and paid $300.00 for a consultation fee. He said to continue with his services I would have to come up with $$5000.00 retainage by Friday, which I did. The only thing the lawyer did was write a letter to the judge, write a letter to the judge to retract the first letter and then a letter to the judge saying I released him of his services. I saw him (1) time for (10) minutes to explain I wanted to continue with the divorce and he explained I needed to write him (2) letters, which I did. I dont believe its fair that he took all of my retainage for doing nothing. He also hasn''t given me any of the paperwork from the divorce decree to the letters that were written on my behalf. What are my rights and what can I do??
