Have you contacted them and tried to discuss payment arrangements?
Do you work now? The reason I ask is because your accounts are being levvied instead of your paychecks being garnished probably because you filed unemployment at some point. The creditor more than likely wasn't able to find current job info on you, and unemployment checks can't be garnished for consumer debts like a credit card.
This is interesting, because about 2 months ago I dealt with this situation with an employee..I received a writ of garnishment for them, and they had an accident on the job and had to take disability before I could even file the writ. I had to provide notice and verification of this to the creditor, and the creditor immediately being the levvying process. Well, the employee was very angry, and when he was able to work again, he got a bit loud with me.

I explained what happened and what I had to do, and he was able to contact the creditor, unblock his accounts, and start the garnishment again.
