How to Escalate a Complaint

1. Call (832) 442-2200 or your local office — get a case number. Use wasteconnections.com/locations to find your specific local office for faster escalation.
2. Send certified mail for commercial contract disputes — cancellations, auto-renewal disputes, and rate increase objections require written notice per most Waste Connections contracts (30–90 days). Send to the local office AND the corporate HQ simultaneously.
3. File with the BBB under your local service market’s BBB chapter. Top complaint patterns: post-cancellation billing, unauthorized rate increases, missed pickups, and poor call responsiveness.
4. File with your state PUC or solid waste agency — in many states, waste haulers are regulated and subject to service quality and billing enforcement.
5. File with your state AG for deceptive auto-renewal practices and unauthorized rate increases.
6. Dispute unauthorized charges with your bank or credit card — ACH disputes within 60 days, FCBA disputes for card charges. Document all cancellation notices and contacts.
7. Contact your municipality if you’re on a municipal franchise — city or county solid waste departments can intervene directly with the franchisee.
8. File with the FTC at reportfraud.ftc.gov for systematic auto-renewal and cancellation abuses.
