How to File a Complaint Against National Financial Services LLC
Step 1 — Contact NFS Customer Service Directly
Call NFS’s main customer service line at 1-800-752-7053. When connected, press 1 for investor account inquiries. Clearly describe your complaint, provide your account number and all relevant details, and ask the representative to formally log your concern and provide a case reference number. Most billing discrepancies, 1099 errors, statement issues, and account disputes can be initiated and resolved at this first stage.
Step 2 — Request Escalation to a Supervisor
If the first representative cannot resolve your complaint, immediately ask to be transferred to a supervisor or senior account representative. Senior representatives have greater authority to initiate formal investigations, escalate to the back office, and authorize remedies that frontline agents cannot process. Document all supervisor names, dates, and commitments made.
Step 3 — Submit a Formal Written Complaint
For a written record of your complaint, write a formal letter to National Financial Services LLC, 245 Summer Street, Boston, Massachusetts 02210, Attn: Client Services.

Step 5 — File a Complaint With the SEC
File a formal complaint with the U.S. Securities and Exchange Commission at sec.gov/tcr. The SEC accepts investor complaints involving securities fraud, account misconduct, and brokerage rule violations. Filing with the SEC creates an official federal record of your complaint.
Step 6 — Contact SIPC
