Well it all depends if the accounts are legit and you are willing to pay for them. If they are you have three options.
1. Don't wait for them. They have the upper hand. Contact them and work out a settlement. Ask for everything is writing on what you settled on.
2. Make them validate the debt. If some time pasts call them to see the status of validation. In this case prepare to get a lawyer. Paying $2000 for representation is a lot better than paying the debt. And if they don't really have the right to collect the lawyer might scare them off. Make sure everything you send is cerified mail.
3. Wait until they sue you. Again GET a lawyer ASAP and be ready when this comes if you feel you have the upper hand.
If it's not legit try the validation game. I did and it worked twice. If they persist you have to get a lawyer to defend you. Then sue them for breaking the law.
Now I now some are saying "But I'm still spending money if I get a lawyer" Yes you are but you are saving yourself the headaches and them just taking your money without warning. Trust me I'm going through it right now and it's a big headache trying to hide your money, pay bills, and just live without getting phone calls and a ton of letters from collectors.
A friend of mine did the DV thing and just waited for them to contact her. They never did. But this is what happened out of the blue. 1. They garnished here wages $400 a month. 2. Took $4000 from her bank account (Cleaned it out) 3. Put a lean on her house now she can't sell it. This all happened last week too.
So be careful people. Hope I helped you dfawaz.
