Under the Fair Debt Collection Practices Act (FDCPA), you have the right to request validation of the debt. Within 30 days of the initial communication from the debt collector, you should send a written request asking them to provide you with information such as the name of the original creditor (the telecom company), the original account number, the amount of the debt, and verification that you owe it. Kramer Law Firm can help you draft a debt validation request letter and advise you on how to proceed based on the collector’s response.
