Uncomfortable interaction with xfinity chat

I was trying to set up the modem I received. I chose to go through xfinity chat for help. The representative didn’t even ask if I had it plugged in, yet said it needed to be upgraded. In order to upgrade I needed to agree to the terms and sign, and that my bill would remain $70. My bill is $45 so I asked why it would be $70. He then said it’s $25/month for the upgrade and I didn’t have to do it and this upgrade could be done without paying the extra $25/month. I repeatedly said no and he said he respected my decision, yet repeatedly continued to ask me to sign up for it. Then as he was “upgrading” the modem, he started telling me personal things and sending heart emojis. A lot of heart emoji’s were being sent. He was clearly trying to manipulate me. I’m sure this wouldn’t have happened if I was a man. He wasn’t being upfront about information and instead tried talking about how good of energy I have. Again, inappropriate. I feel weird about the entire exchange. At the end he said “the signal” was saying I needed a tech appointment for someone to come to my home. He never said it would cost $100. This was the only option he gave me. He did not help me at all. The conversation ended with him wanting to ask me questions about his assistance. When I didn’t respond he continued to message me with heart emojis.
