In the year 2013 my family and I lived in XXXX XXXX Apartments and paid the first month of rent, and the deposit. We always paid the rent for a year since the apartments were under contract. We never missed any payments and the water payment ; we paid it full. I even have proved that we paid it all. I have the confirmation number that we paid it. Recently, I received a letter from the National Credit Systems , Inc regarding the deposit that we did n't pay. The amount is {$690.00}. They have sent me to collection without any warning or any prove that I owe that amount. In the letter it says they have already reported this collection to XXXX national credit bureaus. Please I need your help to clear my credit and erase this debt that I do not owe.
