After a free consult w/ a bankruptcy attorney he quoted fee of $3k of which 50% had to be paid to file by 2/28?

I paid $1040 2-4-11 of $1750 needed before 2-28. Then on 2-23-11 decided not to file bankruptcy & requested a refund. I received an itemization 3.5 hrs & refund of $165. I was billed at $250/ hr including charges for the free consult. I disputed the refund indicating I didn't sign a contract agreeing to the hourly rate.i offered 1.5 hrs based on his itemization for hours after the free consultation. I did not provide the doents he requested from me to file the case only the down payment. The attorney admitted as stated on the consult estimate that a separate contract should have been provided to sign upon retaining his services & refunded $500. A contract beyond the initial consult was never provided or signed. Am I entitled to the full amount or at least the amount paid minus 1.5 hrs ? I reposted to clarify the details I am not trying to get away with free legal services but I did not provide the required doents to have any real work done yet I still offered to pay for the 1.5 hrs of service he said he provided.
