Uncomfortable interaction with online chat agent

I chatted with Himani last night to activate my modem. At first they seemed fairly professional. Then they asked for my IMEI number for a special Xfinity Internet deal that was not related to activating my modem. I declined and they became more urgent in asking for my IMEI claiming that I could only get the deal from them while in the chat. After the modem was successfully activated, they typed, "Please help me with the IMEI of the phone now." It was bold in the chat. And then asked that I remain in the chat rather than wrapping up the issue. The next bit made me very uncomfortable because they also used a lot of blushing, kissing, and heart emojis.

"thank you personally as I have never ever interacted with such an amazing person like you. You are very polite and patient throughout the chat today. I wish every customer is wonderful like you.(emojis)" 

That was immediately followed by:

"Could you do ONE thing if you like my help? (excessive emojis) Please judge this chat on my assistance and behavior only :)"

Followed quickly by:

"I would appreciate if you would share your (emoji)Precious views on (emoji)recent chat experience (emoji) by clicking "End Live chat" button at bottom of this chat."

All of that came rapidly in the same one-minute period. I did not respond to any of this and ended the chat.

I've now read several other posts from people with similar experiences with other agents. Please do better at monitoring and hiring your agents. I'm uncomfortable that this person now has my home address and possibly my other contact information.
