Phone trade-in is a scam

In a previous posting about my experience with the phone trade-in program (read it here https://forums.xfinity.com/conversations/devices/urgent-tradein-issue-rejection-and-lack-of-resolution-feels-like-a-scam/677c16387699a97c8906b0fb?commentId=6814746c9ad3b0659f002368 )

I had posted an update stating a deal I had worked out was being honored.  I tried to post a new update but the thread has been closed.  The new update is that the deal was honored for one month but has since been denied and won't be honored for the 23 remaining months it was supposed to be.

So, even though I have a recording of an Xfinity billing supervisor spelling out exactly the discounts to be given me (he acknowledges he knows I'm recording on the tape btw) Xfinity won't honor it and doesn't have to because it wasn't written out.
