The company, Enhanced Recovery, reported an XXXX XXXX XXXX bill in XXXX of 2014 without sending a dunning notice. This was a debt that they had previously tried to collect from me years before and was eventually deleted from my credit reports after disputes were not validated on their end. They began reporting to XXXX and XXXX in XXXX of 2014. I disputed through the XXXX and they acknowledged through written message that they did not send a dunning notice because they were unable to reach me on a cell phone number they had listed as my contact. So as of last week ( XXXX XXXX ) they sent the dunning notice-5 months AFTER they began reporting this on my credit reports. I was not given the chance to dispute before this was marked as a derogatory item on my report and sending the notice now is a clear violation. I want this debt removed from my credit reports as it is being reported incorrectly and collected in violation.
