Existing customer needs help downgrading 2-Gig internet plan

I’m currently paying approximately $149 per month for HSD Gigabit 2X internet, with speeds up to 2100 Mbps download and 300 Mbps upload. I want to downgrade to a 1-Gig plan while keeping unlimited data and the Wi-Fi Gateway.

I’m a verified college student and Diamond member. Please review my account for student, existing-customer or retention pricing. I would also like confirmation of the new plan’s exact download/upload speeds, complete monthly price and the length of the offer before making changes.

I have tried phone and chat support multiple times, but the agents disconnected or redirected me to the automated assistant. An official Xfinity employee’s assistance would be appreciated. I can provide my name and service address privately through direct message.
