Received a letter from American Coradius International LLC stating that I owe them for a collection for XXXX. The amount that it 's states I owe is XXXX. I checked my account on XXXX and it states my balance is {$0.00} and I do not have an open credit card account on XXXX. I did a credit report and not does it show I have an open account at XXXX indicating my identity has not been stolen. I do not know why I received this collection unless it is a mistake on their part and I do not want this to effect my credit.
