you can talk to an agent online through chat. I was in the same position as you and i don't like talking through phone as much. When i was chatting online with an agent i asked about what offers thay had and what other services i could get. Sometimes you'll get lazy workers that will only give you expensive offers. But luckly the second time i chatted with a customer service agent they gave me the option to upgrade my internet with a 1 year contract and stay with the same price.
When you go online and try to change your services it will take you to a page that says you either have to click on xfinity assistant or call a number. click on the xfinity assistant option and it will take you to a chatting page where it will connect you to an agent.
