If Bill pay page won't load How to Pay a Bill with Xfinity Chat assistance

1. Sign in to your account and select "Contact&Support" from the Xfinity menu bar along the top of the page.

2. In the box "Chat with Xfinity" click the link "Chat with Xfinity assistant" 

    The chat box will appear in the lower right of your screen

3. type "billing" in the area that says "message..."

4. NO MATTER WHAT IT ASKS NEXT type "agent" in the message box and you will be connected to a live agent.

5. Tell the agent you want to pay your bill and get a receipt. Add that you know you have to give consent and a manager will process the payment while you are with the agent.

6. you can have the receipt texted or emailed to you if they have that contact information on your account.

7. shmooze with the agent until they give you the confirmation number and compare it to the receipt while they are with you in the chat.

8. You're all done within about 20 minutes, which is pretty good for a chat. 

It was my first time trying this in desperation and it took quite a bit longer because I had to ask a bunch of questions to understand the process so it would go quicker next time. I hope it works for you and anyone else that reads this!

Good luck. ;-)
