Capital Recovery Services I made a settlement agreement with this company on a credit card and they ripped me off of more than 3,000 dollars Huntington Beach California

I was contacted by capital recovery services on an old credit card account from 1998 saying I owed twice the amount that was on the card but they made a settlement with me over the phone and I even had them send me proof that they owned the account and they did.

Here's the deal they accepted from me , a one time overnight payment of 3,000 dollars , then $25.00 (30) days from that date every month for a total of 84 payments until total remainder balance was paid off.

Now I just received today july 20, 2009 a civil summons to appear in court from another agency saying they represent the credit card's bank and the account and they are sueing me for the full amount. I don't know what to do!

Someone please help me!!!!
