Free peacock premium reward not working

I’m a platinum member and have been unable to get my free peacock premium reward. My rewards page says it has been claimed. When I clicked the link in xfinity assistant it took me to peacock. I signed in and all seemed good. But when I closed the app and tried to open it again it said I do not have a current subscription. It gives me two paid options to choose. Peacock says it’s an Xfinity issue and I do not have a current subscription. I have been in contact with a live agent at Xfinity at least 4 times and tickets issued. Never hear back and issue still not resolved. I’m very frustrated that I can’t get the free subscription that I qualify for. Can someone please resolve this for me.
