I got a letter from performant in California stating I owe them$423.99 for unpaid taxes in Louisiana in 2005.. so I called Louisiana revenue and sure enough I owed them.. I went ahead and submitted the payment using my debit card to Performant thinking my account was closed and paid off until I got this letter today it's saying I stilled owe them $429.99, but this time the return address on the envelope was from performant in Aurora Illinois.. I don't know what's app can anybody out there help me or at least give me some advice.. respectfully, Jimmy Sullivan
