Escalation steps — if you’re not getting help
Follow these steps in order:
If calling didn’t fix the issue, try live chat or DM @ADT on X. Ask clearly to speak with a supervisor or customer relations specialist.
ADT has a verified BBB profile. Many customers report getting a callback from ADT’s Customer Relations team within 24 hours after filing. File here: BBB — ADT Security Services. This is often one of the most effective ways to resolve billing disputes, cancellation issues, or service problems.
Every U.S. state has one. ADT must respond to official complaints. Find your state office at naag.org.
For deceptive practices, unauthorized charges, or contract violations. File at reportfraud.ftc.gov.
If someone shows up claiming to be from ADT and it seems suspicious, call (800) 238-2727 immediately before letting them inside. Also report it to the BBB, local police, and warn your neighbors. See ADT’s fraud page for guidance.
FTC Cooling-Off Rule: If you signed an ADT contract in your home, you have 3 business days to cancel without penalty — no matter what the salesperson says.
