anyone else promised a free phone on 9-11-2021 and now being told...nope, not free?

On 9-11-2021, I called Xfinity cable to update my internet service. The person on the phone offered me a "too good to be true" (literally, it was not true) offer to switch from my mobile phone carrier (Google Fi; who is awesome, by the way, see here: fi.google.com) to them. I would get:
-Free phone for my daughter, who did not have a phone yet (Not true, I was told in December.)

-I would pay for a shared data plan and only pay $5/gig if/when we went over. (Google Fi charges $10, so I thought I was getting a bargain. NOPE...they have been charging me $15).

After visits to the store to set up our phones later in September ( during which no one told us the deal was bogus), we started looking at our bills and wondering what was happening. We visited our local store once (Dec 5th) with a promise the manager would follow up after our visit (but did not) and twice (Dec 28th). Then we switched back to Google Fi (seriously, check them out. They treat me like a human.) 

We know Xfinity likely recorded our phone call. But we also know they have a legal team. And we don't. What we do have is a bill for a $399 phone ($319 remaining) that we are now being told we cannot return because we are outside of the return window. And we have a new carrier, again, Google Fi, people. CHeck it out.
