Lower-cost internet plans

I want to review lower-cost internet plans for my account in writing before making any changes. I am currently paying $154.66/month for Gigabit X2 + xFi Complete and would like written pricing for 300 Mbps, 500 Mbps, and 1 Gig options, including total monthly cost, upload speed, unlimited-data terms, equipment fees, and promo duration. I do not want to authorize any plan change yet. Please have an Xfinity employee assist me privately with account-specific options.
