Arbitration dismissed, what now?

I replied to the notice from NAF and to the lawyer that I am currently in a debt settlement program

This credit card is one of the card in the program. However, my settlement company has not yet settled with them as there is not enough money in my account with them to try to settle this debt yet.
I have not sent this credit card any payment since I joined the settlement program.
The credit card company does know that I am in the program re: my letter to them and to the NAF and they were also notified ages ago that I am in the program.
Thank you for your info.

It probably means that you didn't respond properly to the notice of arbitration. Arbitration is mandatory and binding, it's a substitute for taking you to court, without having to actually do it. Once there's an arbitrator's award, that can be enforced simply by registering it as a judgment in a court local to you, and then proceeding to garnishment, judgment debtor interrogatories, writs of fieri facias, and seizure of property.

You really need to see a lawyer in your area now. You're waaay behind the eight-ball. Telling them that you're in a debt settlement program don't mean spit, unless that particular creditor has already agreed to go along. If the latter is true, then you need to state that in a legally cognizable way with the arbitrator. If I were in your position, I'd file my own notice of arbitration and file a petition with the local court to appoint an arbitrator.
