On XXXX XXXX, XXXX, I sent a certified letter to XXXX XXXX. XXXX, vice president/trial counsel of Fidelity National Law Group, assignee to XXXX Receivables requesting them to verify a debt that has started in XXXX, but until now I have not received anything from them. They placed lien on my property in XXXX and XXXX but failed because the SSN who owes the debt was not mine. They also tried to foreclose on my property thereafter, and that also failed. This debt was not even ever in my credit report. What should I do next? Will you please help me?
