Link Expired While Updating My Plan

Hi, I hope you are having a good day. I was talking to an agent to change my plan and received a link by email. The email said the link would expire in 72 hours. I had to step away for a few hours, and when I came back and tried to use the link, it no longer worked. I wonder if there is a way to receive the link again or reconnect with the agent.

I am sorry for the inconvenience, and thank you for your service. This is my previous post: https://forums.xfinity.com/conversations/customer-service/question-about-internet-plan-pricing/6925d62a2714ca557110bf86
