According to my credit report the original account is labeled as a "revolving charge account". It is pretty much like a credit card. It was also my understanding that the Statute of Limitations (SOL) in Arizona for these types of accounts is 3 years. I got my information from a book by Kevin Trudeau.
BTW, I have already received a message from LVNV via the Better Business Bureau which contained a few old billing statements. This message also states that this account was "charged off" on May 31, 2012 with a balance of $420.00. LVNV is now claiming that my balance owed is just over $1000.00.
If I do go to the courthouse I'm positive that their case files will reflect much of this same information.
What do you think I should do now? Should I try to negotiate (per the recommendation of Dogmatique)? Doesn't LVNV have to prove that they own the debt?
