Xfinity "Branded Partner" Telling me if I decline the free mobile line my 5 year price will be $60/more per month. Is that true?

Right now Xfinity has a promotion for internet. (https://forums.xfinity.com/conversations/announcements/what-to-know-about-the-new-5-year-price-guarantee/684b3bc477fc803178153c7e) Price lock if $50/mo for 5 years. I signed up online and declined the free mobile unlimited line.  I declined because I have a phone service I'm happy with and I didn't want to have to worry about cancelling before trial period was up. It didn't change the final prices I saw. I was emailed a confirmation saying my first bill would be $51.28 per month:

I went to the Vancouver WA Xfinity on hazel Dell to pick up my modem and the sales rep (Christeen) there tried to push the mobile line on me and claimed that if I didn't take the mobile line the price of Internet would increase to $110. I showed her my order confirmation. She said look at the fine print. I did and didn't see anything that corroborated what she was saying. I read the fine print to her aloud:

"
You are eligible to receive an included Xfinity Mobile Unlimited line for $0.00 for 1 year. To claim this included line, you must purchase Xfinity Mobile within 90 days, and the Unlimited line must be activated within 1 year of purchase of Xfinity Mobile. To continue receiving the included line discount, you must keep Xfinity Mobile with an unlimited plan and 300 Xfinity Internet service or a higher tier of Xfinity Internet for 1 year. If you change all Xfinity Mobile lines to By the Gig, or cancel Xfinity Internet, or change Xfinity Internet to a tier below 300, you will no longer receive the included line discount."

This says if I don't keep the internet, I will lose the discount for the mobile phone. It doesn't say if I don't keep the mobile phone, I will lose the discount for the internet. I explained that to her. 

Her manager agreed with what she was saying (lose the mobile phone, internet price increases to $110/mo). . As I was leaving she (blonde haired lady) said "Did you tell him that his price is going to increase if he doesn't take the mobile line?" 

Who is correct?
