What to do if your lawyer quits 3 weeks before trial..?

My husbands lawyer submitted a motion to be removed from his case in court, when the judge asked why he begin to basically state the reason was because my husband questioned him regarding how the case was progressing. When the judge asked my husband if he objected the lawyer cut him off, begin yelling and callling him names. The judge through the lawyer out of the court room. The lawyer is no longer on the case and is also refusing to return money we paid him to work the case. Trial starts in 3 weeks, what are our options. Note: we have paid him about 7000 dollars to date and were completly up to date on our payment( actually ahead by 2500 dollars) the total charge for the entie case was 10000 dollars.
