I am filing a complaint against State Collection Services, XXXX XXXX XXXX XXXX, XXXX wi, phone XXXX. State Collection Services placed a derogatory item on my credit report XX/XX/XXXX.I have never received any correspondence, bills, notices, phone calls, or any other attempt to reach me before this action took place. I called State Collection Services and they informed me that it was for a medical bill, from XX/XX/XXXX. They could not verify the details. I have been at the same address for XXXX, same phone for at least 10yrs, and nothing was sent to me regarding this Item. I have requested Validation of the Claim from both the Collection company and XXXX. The action of affecting my credit rating without making a reasonable attempt to make any contact seems at the very least inappropriate and at its worst- likely unlawful. In speaking with the representative from State Collection Services, I was able to learn that the claim is a medical claim, but they could not provide any further documentation. They would have to request that information. It seems that to put an item on a credit report without a satisfactory attempt to reach me and without having the details of the claim, should be brought to your attention. thank your
