Can a Bill of review be done after my bank account got garnished just now (march 2012) since I was never served in 2005? What are my chances in court?

Sometime in 2002 or 2003 my credit card company wrote off my debt and sold it to someone else and they sued me in civil court and entered a judgement against me in 2005 which I recently found out when my bank acct was garnished last month (march 2012) I have hired an attorney to help me with the case but I need to get a second opinion. I was never served and my attorney says that he can file a bill of review. What are my chances of winning this case since I was unaware of the fact that I was sued? Also, the attorney for the creditor does not want to settle since they were able to get about $4000.00 out of my bank account and they think they can get more out of me. Credit card may have been for no more than $3000.00 to $5000.00 max but they have added ridiculous amount of interest and penalties and now it shows about $18000.00 and accruing interest daily.
