I contacted LVNV about an old debt that I was tricked into paying after statute which is being paid as agreed. While I was talking to her, she found another old credit card debt from 20 years ago which was paid to a different creditor, but is back on their books with outrageous interest. The statute of limitations is 6 years in our state. They sent me a letter demanding a response within 30 days or they will take legal action against me for a 20 year old debt that was already paid to a different creditor. They are basically bullies taking people 's lunch money. I do not know whether to reply or not. The last time I replied to LVNV about a 15 year old debt out of statute, they sued me and I am still paying it. The amount is easily XXXX the original amount owed to the credit card. Our local judge just pushed these through and takes the money for the local court. Please help us. 
Thank you for your time.
