About Spectrum
Spectrum is not a standalone legal entity or publicly traded company. It is the brand under which Charter Communications sells all of its consumer and small business products, including Spectrum Internet, Spectrum TV, Spectrum Mobile (an MVNO on Verizon’s network), Spectrum Voice, and Spectrum Business. Charter was founded in 1993 and grew largely through acquisitions, most notably the $55.33 billion merger with Time Warner Cable in 2016 and the simultaneous acquisition of Bright House Networks, which together created the second-largest cable operator in the United States.
As of December 31, 2025, Charter served 31.8 million customer relationships and 29.7 million internet customers across 41 states, generating $54.8 billion in full-year 2025 revenue. In July 2025, Charter and Cox Communications announced a definitive agreement to combine their businesses, a pending transaction that would create the largest cable and broadband operator in the United States by subscriber count, with all customers served under the Spectrum brand. The company is led by President and CEO Christopher (Chris) Winfrey (since December 2022), with Jessica Fischer as Chief Financial Officer.
Spectrum in Michigan and the chartermi.net Domain
Searches for chartermi.net come almost entirely from Michigan residents looking for Charter. chartermi.net was the email and web domain of Charter Communications’ original Michigan cable systems, and long-time Michigan customers were issued @chartermi.net email addresses before Charter rebranded all consumer services under the Spectrum name.
If you still use a chartermi.net email address or need records from an old Charter Michigan account, call Spectrum customer service at 1-833-267-6094 (24/7) and ask the representative to look up your account from the legacy Charter system. Have your old account number ready if you have it, because legacy records are sometimes stored under the original Charter customer ID rather than your current Spectrum account.
There is no separate Spectrum corporate headquarters in Michigan. Michigan customers are served through local Spectrum retail stores across the Detroit metro area, Grand Rapids, Lansing, and other markets, along with the national phone lines listed below.

How to Escalate a Complaint to Spectrum Corporate
- Call 1-833-267-6094 first. Document the date, representative name, and case reference number. For billing disputes, cancellation reversals, unreturned equipment fees, or repeated outage credits, request a supervisor on the first call.
- Ask for the Retention or Customer Advocacy team. These teams have greater authority to apply credits, waive fees, and adjust account terms.
- Use the Spectrum app and online chat. Live chat creates a written record of all communications, which is more useful than phone notes when escalating further.
- Send a certified letter to the Stamford HQ. Write to Charter Communications, Inc. (Spectrum), Customer Resolution, 400 Washington Boulevard, Stamford, CT 06902. Include your account number, prior contact dates and representative names, and the specific resolution requested.
- File with the FCC. Charter must respond to FCC complaints within 30 days. File at fcc.gov/consumers/guides/filing-informal-complaint.
- File with your state Public Utilities Commission. State regulators can investigate billing fraud, service quality failures, and contract disputes.
- File with the FTC or CFPB. For deceptive pricing or misleading offers, use reportfraud.ftc.gov; for Spectrum Mobile billing and financial service disputes, use consumerfinance.gov/complaint.
- Contact the BBB and your state Attorney General. Spectrum is listed with the BBB (bbb.org), and many state AGs actively investigate cable billing practices.
