This company has refused to VALIDATE a collection that they have had on my credit report for years now. This brought my score down, they can't tell me anything about it, who the patient was, where the service was provided. And when I sent them the insurance information to bill Insurance, they refused hoping I would pay the entire bill. I sent a settlement check in just to get this closed and off the credit report, they sent a snob letter stating they are holding onto the check and waiting for the rest of the payment. On the memo area, terms were this was payment in final of account. The have not been able to validate the services provided and do not comply with the Validation laws. I was able to get this off my credit report. So then THEY ENTERED IT AGAIN WITH A NEW CURRENT YEAR DATE so it looks like a brand new account. I thought this was against the law. Medicaid paid the bill, this is the balance that the hospital is to right off, instead they are coming after a sick mommy for the rest of the payment. Again, I believe this is against the law. I have asked for the audit of the account and they have not compiled. This company is very shady, they are affecting my credit score as I am trying to get my boys into Section 8 housing as I have heart problems and can't work anymore. This company is one of the shadiest they come. NOT TO BE TRUSTED.
