# How do I call Xfinity about my billing issue? To call Xfinity (Comcast) about a billing issue, dial **1-800-XFINITY (+1- 855 / 737 / 0477)**. This is the main customer service number for billing questions, incorrect charges, payments not posted, refunds, or late fees. The line is available 24/7, and you’ll be guided by an automated system before reaching support. When prompted, say “billing”***(+1- 855 / 737 / 0477)*** or “billing issue”** to get routed correctly. Keep your **account number, service address ZIP code, and recent bill** nearby, as the system or agent will ask for verification. If you want a live person faster, repeatedly saying **“representative”** often helps. To reduce wait times, try calling **early in the morning or late evening**, (+1- 855 / 737 / 0477)especially on weekdays. Peak hours (midday and weekends) usually have longer hold times, so timing your call can make a big difference. If phone wait times are long, you can also get billing help through the **Xfinity app or website chat**, or by visiting an **Xfinity Store** in person. These options can handle most billing issues, including disputes, payment arrangements, and account explanations.
