I sent a debt validation letter to an attorney's office which has a small account ($115.50) of ours. They then sent me a letter with the account number and balance also stating this is the FINAL demand for payment or it will hit my credit....Well, it has already hit my credit. And from what I can tell this is not valid proof of debt as there is no copy of the original contract or proof that the medical facility gave them the permission to have this account. So, my question is..What do I do now? Do I contact the CA or just wait until the 30 days is up to move on..? Any advice is greatly appreciated.
