unable to activate peacock premium that I claimed through Xfinity Rewards

I claimed peacock premium through Xfinity Rewards (platinum customer).  I received an email to activate through Xfinity assistant.  When signing into the assistant, there is no banner to activate.  It states on my bill that I have it, but on my xfinity box no subscription. I have called Xfinity and they have opened a ticket, but still nothing.  This whole process is very frustrating.  It should be very simple.  Please help.
