Peacock via Xfinity Rewards

I have previously claimed free Peacock for being a diamond rewards member and after activating I'll get the dreaded "upgrade to watch" message after a couple days of it working. Have been in a private chat several times before and the issue never gets resolved. It got to the point where I just gave up and reactivated it whenever I needed to. Now I can't even do that as it doesn't seem to recognize my email. I just want to have what was offered thru the rewards program. Can anyone help? Thanks
