A. 1. Review your contract: Go through your contract and any promotional materials to identify any fees that may not have been clearly disclosed. 2. Ask for a breakdown: Contact customer service and request a detailed breakdown of your bill to understand all charges.

B. 3. Set up alerts: If your billing system allows, set up alerts for when your bill is generated or when payments are due to keep track of your charges. 4. Monitor your account: Regularly check your account statements to catch any unexpected charges early.
