How to File a Complaint Against ADT Security Services
Customers may need to complain about billing, contract terms, cancellation, alarm performance, installation, equipment, sales practices, moving service, technical problems, unauthorized charges, or customer-service interactions. Keep the account number, contract, service address, invoices, dates, technician information, and previous case details before escalating.
Step 1: Contact ADT Customer Service
Call 800-238-2727 and explain the problem clearly. Provide your account number, service address, date of the disputed transaction or service visit, and details of earlier contacts. Ask the representative to document the complaint and give you any available case or reference number. For system or equipment issues, describe error messages, alarm events, device failures, or technician visits in detail.
Step 2: Request Supervisor or Specialized Department Review
If the first representative cannot resolve the issue, ask for escalation to a supervisor or the appropriate billing, retention, technical, installation, monitoring, or account-management team. ADT also publishes 800-730-0081 and 866-843-1264 for account management. Keep records of every call, including dates, names, promises, and case numbers.
Step 3: Address Cancellation or Contract Issues Through the Correct Channel
If the complaint involves cancellation, first review the monitoring or equipment agreement because cancellation rules vary by plan and installation type. Certain current DIY terms specifically direct cancellations to 888-392-2039, while other ADT agreements route service changes through 800-238-2727. Ask for written confirmation whenever service is cancelled or contract terms are changed.
Step 4: Send Formal Written Correspondence to ADT Headquarters
For a serious unresolved complaint, written correspondence can be sent to ADT Inc., 1501 Yamato Road, Boca Raton, FL 33431. Include your name, service address, account number, contract details, dates, previous case numbers, disputed charges, and the specific resolution requested. Attach copies rather than originals of bills, contracts, emails, and other supporting documents.
Step 5: Use the Appropriate External Complaint Process if Necessary
If the matter remains unresolved, the outside process depends on the issue. Billing disputes may involve the customer’s card issuer or financial institution, alarm-company licensing complaints may involve the relevant state regulator, and general consumer disputes may be submitted to a state Attorney General or consumer-protection agency. ADT’s current terms also identify the California Department of Consumer Affairs Complaint Assistance Unit at 800-952-5210 or 916-445-1254 for qualifying California consumer matters. Preserve contracts, billing statements, service records, and ADT responses before escalating.
