You need to file a Motion to Remove Entry of Judgment of Default. You need to recite some law that the courts prefer adjucidation on the merits rather than technicalities. You also need to submit an affidavit signed by you reciting the facts you have posted. You need to do this ASAP. I am not licensed in GA, but in my jurisdictions I have found the above process to work, but such documents must be filed very soon after the actual default.
Sometimes, not always, I have found that the opposing attorney(s) might assent to my motion to remove default. Some jurisdictions call it a motion to 'strike' default.
It would be best to retain an attorney.
This answer is offered for informational purposes only. It is not offered as, and does not constitute, legal advice. Laws vary widely from state to state.

When you find out that a judgment has been entered against you, normally by discovering that your wages are being garnished or the bank account has been frozen, you still have a couple of options.
In most States the Courts allow you to reopen and challenge a “default judgment”. Most States will allow a year to accomplish this. If you did not get the paperwork for the lawsuit, or you got the paperwork but never did anything, then the judgment was “entered” due to your default to file an Answer.
You have to bring a motion in the Court where the judgment is filed. That motion normally has to include a defense to the charges and a copy of your proposed Answer.
You should definitely get a local lawyer to help you with this, or seek the assistance of a Bankruptcy attorney to get rid of the liability. If you can’t afford a lawyer and you are being sued check out my website for a free form Answer.
